A method of controlling a vehicle includes, in response to vehicle speed being approximately zero and a driver braking torque request being greater than a park interlock threshold, commanding vehicle brakes to provide an augmented braking torque. The augmented braking torque has a magnitude that is greater than the magnitude of the braking torque request. The braking torque returns to the level of the driver braking torque request following completion of a gear shift event.

A method and system for determining a maximum cornering braking threshold for a motorcycle includes determining an absolute lean angle with respect to horizontal and a relative lean angle for the motorcycle relative to a road surface. The maximum cornering braking threshold is determined from at least the absolute lean angle and the relative lean angle. The maximum cornering braking threshold is used to provide stability during motorcycle cornering. A multi-dimensional look-up table stores different maximum cornering braking thresholds that correspond to different combinations of absolute lean angles and relative lean angles. The relative lean angle is determined by processing video data from a video sensor. Values for additional conditions, such as motorcycle speed, wheel slip coefficient, steering angle, mue and type of road way are stored in the multi-dimensional look-up table to assist in determining the maximum cornering braking threshold.

A Hill Start Assist (HSA) system for an off-road type vehicle includes a brake system for producing a braking force sufficient to maintain the vehicle in a stopped condition, and a control unit in communication with the brake system for controlling a brake modulator of the brake system to maintain the braking force when a manual brake actuator of the brake system is in a released position. The HSA system is operable in a ready state where the brake modulator is in an open condition and the braking force is not maintained, an activated state and a hold state where the brake modulator is in a closed condition and the braking force is maintained. The HSA system is only in the ready state upon determination by the control unit that predetermined vehicle conditions are satisfied.

A system and method for operating a brake system of a vehicle including determining if the vehicle is stopped. Determining a current brake pressure, a braking deceleration and a dynamic brake pressure corresponding to the braking deceleration. Based on the current brake pressure and the dynamic brake pressure determining a differential brake pressure. A holding brake pressure for holding the vehicle is determined based on the differential brake pressure and operating the brake system with the holding brake pressure.

A vehicle control system may include a mode selector including at least a turn assist mode selectable by an operator of the vehicle to activate a turn assist feature, a controller to employ the turn assist feature by directing application of braking torque to an inside rear wheel of the vehicle during a turn when a trigger condition for implementing the turn assist feature may be detected, and a mu detection module to estimate mu conditions of a surface on which the vehicle may be operating. The controller may further automatically generate a blocking signal to block operation of the turn assist feature responsive to the mu detection module estimating a minimum mu value of the surface that may be less than a threshold mu value.
