Safety car

Safety car(Safety car) isMotor sportsIn, if the machine causes an accident on the course and the car body and parts that have fallen off the road surface are scattered, or the machine body is stopped on the course, race to prevent damage and secondary crash due to the scattered parts. It is the leading car.

Not only in fine weather and cloudy weather, but also in stormy weather such as heavy rain, the organizer may decide to take the lead in the middle of the race.

Overview

IndyCar Series,NASCARGenerally in the United StatesPace carIt is called (pace car).

Normally, it is decided that only one safety car will enter the course in case of trouble.

Incidentally,24 Hours of Le MansDone ofSalt CircuitThe course length is very long likeSuzuka 8 time endurance road raceWhen the number of participants is very large, as in the case above, multiple safety cars may enter the course at the same time.

In addition,Formation wrap,NASCAR-SUPER GTSeen inRolling startIn case of, I will be dispatched and take the lead.

F1 etc.

F1MainlyEuropeIn other races, if the course is blocked by the accident vehicle itself, especially when there is a risk that the other vehicle will step on the debris and the tire will puncture, or the race will not be interrupted In case of a critical situation in safely performing a race such as a heavy rain that makes it difficult for the vehicle to drive, ensure the safety of competitors and officials and control the pace of the competition car A safety car will be introduced for this purpose.

procedure

When the safety car enters the course, yellow on all sections of the course.Race flagIs shaken,SCThe placard and the LED display board that says "" are displayed, and the driver is required to slow down the driving speed. What is "SC"Safety CAbbreviation for ar.

While the safety car is taking the lead after these signals are presented, all competition vehicles are prohibited from overtaking unless there is an unavoidable situation such as when the preceding vehicle slows down due to trouble.

The safety car is equipped with green and yellow revolving lights and flash lights on the upper part of the car body (in the center of the roof or on the rear window).The meaning of the color is exactly the same as the race flag.Generally, it is rod-shaped, with yellow lights on both ends and green lights in the center.The safety car flashes the green light for a while after entering the course.While this light is on, the competition vehicle is allowed to overtake the safety car.When the car running at the beginning of the race (the car in first place at that time) catches up behind the safety car, the safety car switches the lighting lamp from green to yellow.From this moment on, overtaking of the safety car is prohibited.

While leading the convoy, the safety car turns on the yellow lamp and turns off the lamp when it is confirmed that the course is safe and the next time to enter the pit, informing that the race will resume from the next lap.

When the safety car intervenes in the race,Side effectsHowever, even if a big lead is built with the following car before the safety car enters, all such differences will be reduced.Therefore, while there is an effect that the spectators can see the match again, there is an effect that even if the lead is built, it will be wasted due to the safety car intervention, especially for the previous runner.Therefore, it is one of the team's strategies to decide when the introduction of the safety car will be canceled and whether or not the driver will finish the pit stop during that time, and in some cases it will greatly affect the outcome.[1].

However, although the safety car is introduced only to ensure safety, there is an opinion that the safety car actually has a great influence on the competition itself and the result, so depending on the competition, it is not until the safety car is released. If there is no such condition, intermediate measures such as "virtual safety car" and "slow zone", which will be described later, are being sought.

History in F1

The first safety car race in F1 was in 1973Canadian GPIs. However, in this race, he accidentally took the lead in front of a driver who was one lap behind, which caused confusion in the race, and it took several hours after the end of the race to determine the winner.

after that,1992 ToregulationThe rules are officially established by the revision.1993 OfBrazilian GPIt was introduced for the first time after it was enacted.

At that time, the safety cars used were those prepared by each circuit. However, since the performance of the vehicles owned by the circuit varies, if the performance of the safety car is low, the driver in the F1 car that follows will be accompanied by a slower pace of the safety car, reducing the temperature drop of the tires. There were problems such as having a hard time keeping it.

Introducing a Mercedes-Benz exclusive vehicle

The organizer was able to address various issues related to such safety cars.International Automobile Federation(FIA) had a headache.

Meanwhile, the safety cartv setFocused on the high degree of exposure toMercedes-BenzOffered to the FIA ​​to supply a safety car. This1996 Or later,AMGVehicles made by us are provided free of charge, including maintenance costs such as maintenance costs, and are now used in F1 as official safety cars[2].. At the same time, the medical car is also provided by AMG mainly based on the C-class wagon model.

Two cars will be brought to all Grand Prix[2].

The driver will be hired by the FIA ​​and will be in charge of the same person throughout the year.F3championOliver Gavin, After 2000German Touring Car ChampionshipHave experience in racing, etc., and were good at handling similar vehiclesBernd MylenderHowever, I came to do that.

1997 OfCanadian GPAtOlivier PanisWhen a safety car was introduced due to the accident, it was decided that it would be difficult to continue the race, and the race ended with the safety car leading the line. Similar example2009 Australian Grand Prix(Remaining 3 lapsSebastian VettelとRobert KubicaIs entangled and crashed),Same year Italian Grand Prix(Lewis HamiltonHas crashed in the final lap).

This vehicle for a safety car is basically the same as the commercial vehicle of the same name made by AMG, but its contents are basically different. Especially,Vario roofThe adopted models (SL, SLK) have a fixed roof with the opening/closing unit removed, which is fundamentally different from the vehicle body structure. However, AMG also accepts sales of vehicles with the same performance as safety cars as a special order (Europeonly).

From 2021Aston MartinHas entered the supply of safety cars and medical cars, but the supply from Mercedes continues and the two companies are using together.[3].

Successive base vehicles (partial)

Performance

Since the safety car has the role of leading the race safely, there is no opportunity to fully open the car, but the leading platoon is a competition vehicle, so it is a high-performance vehicle with a margin in performance. Is required.

In the past, cars that raced were far superior to safety cars in performance. As an example, from the 1980s to the 1990sGroup CWas contested by the carAll Japan Sports Prototype Car Endurance ChampionshipAccording to (JSPC), if you drive at the slow pace created by the safety car, the fuel consumption of the race car will be lighter, and fuel consumption will reach a maximum of 17-18km per liter. At this time, the fuel efficiency of the safety car was said to be about 4-5 km/l, and the performance difference was remarkable.

However, there are regulations on race vehicles to control speed from the viewpoint of safety, while safety cars do not have to follow the rules that limit their driving performance, and it is prohibited in current F1 machines. Has beenActive suspensionIt is equipped with a large number of electronic control devices such as, and in many categories, it is not uncommon for a safety car to be faster than a formula car running in a race.Especially in bad weather, the difference is likely to be noticeable.

Virtual safety car

2014 OfJapan GPOccurred inJules BianchiThe FIA ​​tested after a major accident (Bianchi died the following year)2015 Decided to introduce a virtual safety car (VSC)[4].

This introduces a virtual safety car dispatch condition, during which the driver is required to slow down according to the specified delta time.[4].

The FIA ​​says, "The course of VSC is initiated by the instructions of the course clerk. In situations where it is necessary to wave a double yellow flag on the course, the competitor or the official may be at risk, but the (real) safety It is used when the car is not in a condition to be dispatched."[4].

Similar to this,24 Hours of Le Mansで2015 There is a "slow zone" introduced more. This is due to the instruction from the course marshall, which introduces a speed limit of 80km/h at only a part of the course.2017 The course is divided into 9 sections, and "slow zone" is designated for one or more sections as required.[5].. Excessive speed in the slow zone is a foul.

Indy 500

Indy 500The "Pace Car" has consistently been held since the first in 1911.Indianapolis Motor SpeedwayHas been selected by the official. The pace car is often a side prize for the winner.

Operation

Pace cars are introduced for reasons such as scattered debris on the course, serious collisions, and changing weather conditions. The entire course is warned of danger and this situation is called “Full Course Caution”.

By 1993 or later, while the pace car is leading the race (first car at that time), a yellow flag is swung and the home straight passes due to obstacles such as debris. The entrance to the pit lane will also be closed unless it is not possible.

History

The pacemaker for the first tournament in 1911 was Stoddard-Dayton, which was piloted by Karl G. Fisher.

The most used in nearly 100 years of historyChevroletThe brand car was first used for a relatively late start in 1948, but since then it has been repeated a number of times, and by 2006, it had appeared a total of 17 times.

Second World WarThe cars that were selected as pace cars more than three times in the subsequent Indy 500 areChevrolet camaro,Chevrolet corvette,, andFord mustangOnly. The most commonly used car is the Chevrolet Corvette, which has run a total of eight times by 2006 (it has been decided to make the ninth start in 8 as well).

As an automobile manufacturer, there is a speculation of advertising effects, so it will be prestige of each company to be selected as the Indy 500 pace car of the year. However, there are some cases in the past where this high “advertising effect” has backfired. Chosen as a pace car in 1971ChryslerCompanyDodge ChallengerHit a signboard beside the course and injured several spectators. The accident was made by the officials of the course, in the orange color for the pace car driver to confirm the braking point.cornOne of the main reasons was the accidental removal of (also known as the flag), but Chrysler was blamed for a long time after that.

WTCC

In many categories, races that include safety cars are included in the race distance, and laps are added, but one race is contested by a sprint of 1 to 10 laps.World Touring Car ChampionshipIn the case of (WTCC), if a similar method is adopted, the safety car run will occupy a considerable proportion of the race, so it will be excluded from the race distance up to two laps and will not be counted as a lap (2 Porting Regulation 2009).

Regarding the driver, since the first time it was held in 2005, the local athletes in the venue were selected every time, and they changed every time, but in the eighth round of the year held in Poe, France on May 2009, 5 , The safety car driver was on the track and driving to the top without any instructionFranz EngstlerAfter a crash with BMW, the need for a permanent driver was discussed, and on July 7, it was decided that Portugal's Brno Correira would be the first to serve. On the 2th of the same month, he made his first debut in the 5th round at Porto, Portugal, and performed his mission safely.

Super Formula (former Formula Nippon)

All Japan Championship held at Fuji Speedway on August 2008, 8Formula NipponIn the second race of Race 7, it started to rain heavily, and the start delay was repeated from 2:15, the scheduled start time, and the race started at 45:16 when the rain was weakening and the safety car led the race. However, the lap continued with the safety car leading, but the rain leg strengthened again and the red flag was posted at the beginning of the sixth lap and the race was interrupted. After that, the rain feet did not weaken and race 35 was ended with a red flag after 6:15. As a result, the race was established by regulationTakaaki MatsuuraWon the championship, but could not cover 75% of the planned race distance, so the championship points were halved.

While many players are pitting in and refuelingAndre Lotterer,Kazuya Oshima,Richard Ryan,Tachikawa Yuji4 players stayed on the course as they were, but the safety car ordered Yuji Tachikawa, who was behind the lap, to reach the end of the road. However, after this mistakenly, the top Lotteler also put forward and instructed him to arrive at the end. Lotterer is standing next to the safety car, waving his hand, and appealing if he is wrong, but in the end he goes forward.

SUPER GT

SUPER GTThen as an official safety car2008 から2014 TheNissan GT-RBut,2015 から2016 TheLexus RC FIs used in all battles, but apart from thisNissan MotorIs based on GT-R,LexusAre participating in RC F based competition vehicles.2017 Then this timeNSXWith Honda NSX, which participates in the base competition vehicle, the vehicles of three manufacturers participating in the GT500 class were once carried around.

In addition, in the 2015th round of the 6 season, when the safety car was introduced, almost all the teams flooded into the pit at the same time, causing heavy congestion in the pit, so the introduction of the safety car was posted from the 2016 season. The rules have been revised so that a long pit stop penalty will be imposed if a pit stop is not possible or a pit stop is made, including instantaneous refueling and a prescribed driver change.However, vehicles that have already entered the pit road at the moment of posting and vehicles that are in the process of pit work can continue the work without any penalty.

However, as a weak point, the safety car time and the number of laps tend to be long because the alignment is done by class in the course of the competition.For this reason, during this time, some teams have had to refuel even if they accept the retirement due to lack of gas or receive a penalty (= almost abandon the game), or the driver cannot be changed by the specified number of laps. There was a danger.For this reason, full course yellow will be introduced from 2020, and if a safety car is unnecessary, this will be applied, and improvements such as shortening the time when the competition stops are being made.
