When driving on slippery road surfaces and the on-board computer makes a determination that proper grip cannot be maintained at any tire due to sudden steering wheel input, braking force at one wheel or multiple wheels is applied and engine output is automatically adjusted, enabling the moment that controls the disrupted vehicle orientation and ensuring vehicle stability.
At standing starts on rough roads where the wheels spin and it is difficult to get going, braking is applied to the spinning wheels and engine output is optimally controlled, thereby appropriately distributing power to the four wheels to support standing starts and acceleration.
In addition, on declines where any given wheel may be above the driving surface and engine braking effectiveness tapers off, without disruption automatic braking is applied, speed is suppressed, and the engine brake starts working.
