Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low- friction surfaces (sand, gravel, rain, snow, ice, etc.). Rear-drive vehicles with sufficient power can induce this loss of traction on any surface, which is called power-oversteer .
This is what is happening when a car 'spins out'. A car susceptible to being loose is sometimes known as 'tail happy', as in the way a dog wags its tail when happy and a common problem is fishtailing. In real-world driving, there are continuous changes in speed, acceleration (vehicle braking or accelerating), steering angle, etc.
fishtailing, where the vehicle yaws back and forth across the direction of motion. spin or spinout where a vehicle rotates in one direction during the skid. understeer and oversteer where front or rear wheels lose traction during cornering, causing a vehicle to follow a larger or smaller turning radius.
Lift-off oversteer (also known as trailing-throttle oversteer, throttle off oversteer, or lift-throttle oversteer) is a form of sudden oversteer.While cornering, a driver who closes the throttle (by lifting a foot off the accelerator, hence the name), usually at a high speed, can cause such sudden deceleration that the vertical load on the tires shifts from rear to front, in a process called ...
The preferred form of LSD for drifting is the clutch type, in "two-way" form, for its consistent and aggressive lockup behavior under both acceleration and deceleration. Some drift cars use a spool "differential", which actually has no differential action at all — the wheels are locked to each other.
The ratios between the slip angles of the front and rear axles (a function of the slip angles of the front and rear tires respectively) will determine the vehicle's behavior in a given turn. If the ratio of front to rear slip angles is greater than 1:1, the vehicle will tend to understeer, while a ratio of less than 1:1 will produce oversteer. [2]
Anderson said that replay assist can be used only if there is no contact to the helmet; since Mahomes' helmet was hit, the officials could not use replay assist to confirm if the contact was forcible.
Hence the total under-steer is 11.0 deg/g minus 6.9 deg/g, or 4.1 deg/g. Negative values are over-steering, positive values are under-steering, for that axle. If the under-steer contribution of the rear axle is greater than that of the front axle you get negative under-steer, which is known as oversteer. The analysis is only applicable while ...
