For example, if the front left wheel rolls over a bump it will compress the suspension on that corner and automatically rotate to the left (toe out), causing the car to turn itself left momentarily without any input from the steering wheel. Another example, is that when most vehicles become airborne their front wheels will noticeably toe in.
Left-foot braking is the favored technique for using opposite lock in a front drive vehicle. A related technique is the handbrake turn, in which the rear wheels are deliberately locked in order to break the friction between the tires and the road, allowing the car to be spun around a very tight bend or junction, etc.
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 ...
Here, a scooter is countersteered to turn left. When countersteering to turn right, the following is performed: [5] [6] A torque on the handlebars to the left is applied. The front wheel will then rotate about the steering axis to the left and the tire will generate forces in the contact patch to the left. The machine as a whole steers to the left.
The back end will swing out and the vehicle will turn toward the inside of the curve. If the steering angle is not changed, then the front wheels will trace out a smaller and smaller circle while the rear wheels continue to swing around the front of the car. This is what is happening when a car 'spins out'.
During fishtailing, [2] the rear end of the car skids to one side, which must be offset by the driver counter-steering, which is turning the front wheels in the same direction as the skid, (e.g. left if the rear swings left) [1] and reducing engine power. Over-correction will result in a skid in the opposite direction; hence the name.
In situations where the vehicle is traveling at high speeds, the DSR system will tighten the steering wheel and lower the steering ratio to allow the vehicle to travel in a stable direction. [ 1 ] [ 2 ] The steering wheel will be set in place rather than having the driver hold the wheel tightly to prevent it from shaking.
Torque steer is directly related to differences in the forces in the contact patches of the left and right drive wheels. The effect becomes more evident when high torques are applied to the drive wheels because of a high overall reduction ratio between the engine and wheels, [ 1 ] high engine torque, or some combination of the two.
