One of the most popular and exhilarating stunts in off-road vehicle driving is catching air off a jump. Unfortunately, once the vehicle is in the air, the driver loses significant control of the vehicle. An electronic vehicle control system is described herein that addresses this problem. The system may include an ABS module, a shock position sensor, and an ABS override module. The ABS override module may be coupled to the shock position sensor and the ABS module. The ABS override module may receive a shock-extended signal from the shock position sensor indicating one or more of the shocks are fully extended. The ABS override module may send a stop-ABS signal that may prevent the ABS module from operating. The ABS override module may additionally be connected to a yaw rate sensor, the brakes, and the throttle, and may automatically control the pitch, roll and yaw of the vehicle.

A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

A method of changing an anti-lock brake system (ABS) control mode includes: determining, by a controller, whether a first stage of an electronic stability control (ESC) of the vehicle is in an off state and a launch control of the vehicle is in an on state, and determining, by the controller, whether a driver intends to slow down an operation of the ABS installed in the vehicle; and when it is determined that the driver intends to slow down the operation of the ABS, comparing, by the controller, revolutions per minute (RPM) of an engine of the vehicle, a vehicle acceleration speed, a vehicle speed, and a steering angle with predetermined threshold values, respectively, and when each of the comparison results is satisfied, changing, by the controller, an ABS general control mode to an ABS sport control mode which slows down the operation of the ABS.

A method for controlling a brake system of a vehicle comprises detecting a failure of a sensor for at least one of the vehicle wheels, checking whether a brake control function is being executed at the time of the failure, continuing the brake control function if a brake control function is being executed and deactivating the brake control function when execution of the brake control function has been completed. If no brake control function is being executed at the time of the failure then executing the brake control function if a brake control function is initiated within a defined period of time after the failure, and deactivating the brake control function after execution of the brake control function has been completed and the period of time has expired or if no brake control function has been initiated within the defined period of time.

A method for controlling brakes may comprise receiving, by a controller, a yaw rate from an inertial sensor, calculating, by the controller, a force correction, calculating, by the controller, a pressure correction, and adjusting, by the controller, a pressure command for a brake control device.

A vehicle combination comprising a tractor vehicle and a trailer vehicle, each vehicle including wheels on different sides of the vehicle and wheel brakes associated with the wheels. A method for controlling the vehicle combination includes determining a yaw rate difference between a yaw rate of the tractor vehicle and a yaw rate of the trailer vehicle; determining, on the basis of the yaw rate difference, that an orientation of one of the vehicles deviates from an intended travel direction of the vehicle combination; and activating a wheel brake of the vehicle on only one side of the vehicle in order to counter the orientation deviation of the vehicle relative to the intended travel direction.

A method for determining a safety-critical yawing motion of a vehicle includes comparing a specification signal representing an ascertained setpoint yaw rate of the vehicle for an anticipated trajectory of the vehicle to a measuring signal representing an instantaneous yaw rate of the vehicle measured based on an actual trajectory of the vehicle, thereby generating a comparison signal; checking whether an amplitude of the comparison signal exceeds a first threshold value and whether a frequency of the comparison signal exceeds a second threshold value; and, in response to the amplitude exceeding the first threshold and the frequency exceeding the second threshold, outputting a yawing-motion signal indicating presence of the safety-critical yawing motion of the vehicle.

Provided is a vehicle turning control device which prevents a target yaw rate from being unstable, even if a control gain is changed in accordance with the magnitude of a yaw rate deviation or a road surface frictional coefficient. This vehicle turning control device includes a target yaw rate correction (32). The correction (32) calculates a target yaw rate with respect to the control gain determined based on a vehicle traveling information, using at least one of a plurality of calculated target yaw rates. The control gain is determined such that, as a road surface frictional coefficient decreases or as a yaw rate deviation increases, a yaw response characteristic approaches a basic yaw response characteristic from an initial yaw response characteristic.

A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.
