The vehicle behavior control device comprises a brake control system (18) capable of applying different braking forces, respectively, to right and left road wheels of a vehicle (1). The vehicle behavior control device further comprises: a steering angle sensor (8); a vehicle speed sensor (10); a yaw rate sensor (12); and a yaw moment setting part (22) in PCM (14) configured to decide a target yaw rate of the vehicle based on a steering angle and a vehicle speed, and set, based on a change rate of a difference between an actual yaw rate and the target yaw rate, a yaw moment oriented in a direction opposite to that of the actual yaw rate of the vehicle, as a target yaw moment, whereby the brake control system can regulate the braking forces of the road wheels so as to apply the target yaw moment to the vehicle.

The disclosure relates to a method for adapting a control strategy of a slip-control system of a brake system of a vehicle in a -split situation, in which different wheel-specific brake pressures, are set at opposite wheels of a vehicle axle. The resulting brake pressure difference is limited. In some examples, to generate a brake pressure request, a maximum pressure difference value deviating from a reference pressure difference with a predefined tolerance value is determined on a wheel-specific basis for the wheels lying opposite one another. The reference pressure difference corresponds to the value of the current low-pass-filtered brake pressure difference, and the brake pressure request for each wheel is determined as a minimum of the wheel-specific brake pressure determined from the control strategy of the slip-control system, and from the sum of the average brake pressure of the wheel lying opposite and the wheel-specific maximum pressure difference value.

A braking force control device is provided which has a control unit that controls an upstream braking actuator that generates a common upstream pressure for four wheels and a downstream braking actuator that individually controls the braking pressure supplied to each wheel using the upstream pressure. The control unit controls the upstream pressure so that the braking pressure of the front wheels is permitted to be higher than a lock pressure of the rear wheels but does not become higher than a lock pressure of the front wheels, and suppresses an increase of the braking pressure of the rear wheels so that the braking pressure does not become higher than the lock pressure of the rear wheels, in a situation where the upstream pressure can be supplied to each braking force generating device but the braking pressure of any one of the wheels cannot be decreased.

A brake fluid pressure control device for a vehicle that can perform fluid pressure control on the brake fluid pressure applied to wheel brakes. It is determined whether the pressure increasing time in the current pressure increasing control exceeds determination time which is set on the basis of the pressure increasing time in past pressure increasing control. If the pressure increasing time in the current pressure increasing control exceeds the determination time, it is determined that the road surface on which the vehicle is travelling has changed from the road surface with a low coefficient of friction to the road surface with a high coefficient of friction.

A minimum risk maneuver brake system for a heavy-duty vehicle is described. The brake system comprising a first axle comprising a left wheel braking device and a right wheel braking device, where the braking devices are configured to apply a pre-determined difference in brake torque over the axle in response to a brake signal.

A vehicle travel control device includes a surrounding environment recognition device that acquires surrounding environment information on a surrounding environment of a vehicle; a vehicle state recognition device that acquires state information on a state of the vehicle; and a travel control unit that performs travel control of the vehicle, based on the surrounding environment information or the state information. When the vehicle state recognition device detects a slip of at least one drive wheel of the vehicle, the vehicle travel control device executes brake LSD control for braking the at least one drive wheel. When the surrounding environment recognition device recognizes snow on a traveling road of the vehicle and a snow melting area and a snow non-melting area ahead, the travel control unit switches an operation mode of the brake LSD control from a first mode to a second mode.

A leaning vehicle includes a leaning body frame, a left inclining wheel, a right inclining wheel, an another inclining wheel, a linkage mechanism, a leaning posture control actuator, a left inclining wheel torque applying unit, a right inclining wheel torque applying unit, and an integrated control device. The integrated control device controls a left inclining wheel torque applied to a left inclining wheel and a right inclining wheel torque applied to a right inclining wheel based on a lean torque applied to the linkage mechanism by the leaning posture control actuator. Alternatively, the lean torque applied to the linkage mechanism by the leaning posture control actuator may be based on the left inclining wheel torque applied to the left inclining wheel by the left inclining wheel torque applying unit and the right inclining wheel torque applied to the right inclining wheel by the right inclining wheel torque applying unit.
