To provide braking-force control capable of suppressing a wheelie of a two-wheeled vehicle by changing braking-force distribution. In a method for controlling a braking force of a combined brake system for the two-wheeled vehicle, a lean angle of a two-wheeled vehicle 1 is detected or computed, and, in the case where the lean angle exceeds a specified value, braking-force distribution to front and rear brake devices 11f, 11r is changed.

A computer controlled locomotive brake (CCB) configured for setting and releasing the automatic parking brakes of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the parking brake unlatch pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all parking brakes are released and the train has sufficient braking system recharge to safely control movement of the train.

Disclosed are a vehicle control apparatus and a control method thereof. The vehicle control apparatus and the control method thereof include an input portion configured to receive an engagement operation signal for stopping from an electronic parking brake (EPB) apparatus and a current wheel speed value and a current acceleration value sensed by a sensing apparatus; a determiner configured to determine whether the engagement operation signal is generated at a time immediately before a vehicle is stopped and thus whether a current state is a first state on the basis of the current wheel speed value; when the current state is determined as the first state, determine whether the current state is a second state in which the vehicle is intended to be stopped on land that is flat on the basis of the current acceleration value; and, when the current state is determined as the second state, determine that the current state is a third state in which it is impossible for the EPB apparatus to determine an inclination; and a controller configured to turn off an inclination determining mode of the EPB apparatus and turn on an inclination determination impossible mode of the EPB apparatus when the current state is determined as the first state, the second state, and the third state, thereby controlling the EPB apparatus to lower a current braking force value of the EPB apparatus to a target braking force value which is set to correspond to the inclination determination impossible mode.

Systems and methods are described for monitoring movement of a trailer relative to the towing vehicle and providing driver-assistance information to the driver of the towing vehicle. The system determines a velocity vector for the host vehicle at a location near a rear of the host vehicle at a defined lateral distance from a trailer hitch installed on the host vehicle. The system also determines a velocity vector for the trailer at a corresponding location on the trailerthat is a location on the front of the trailer at approximately the same defined lateral distance from the trailer hitch. The system compares the velocity vector for the host vehicle to the velocity vector for the trailer and determines, based on the comparison, whether a jack-knife condition is likely to occur. If a jack-knife condition is likely to occur, the system generates a warning signal.

A vehicle stability control device has: a front active stabilizer installed on a front wheel side; a rear active stabilizer installed on a rear wheel side; a turning device for turning the front and rear wheels; and a control device configured to perform load distribution control in conjunction with turning control that actuates the turning device, when a difference in braking force between left and right sides of the vehicle exceeds a threshold value during braking. A first side is one of the left and right sides with a greater braking force, and a second side is the other of the left and right sides. In the load distribution control, the control device actuates the rear active stabilizer in a direction to lift up the first side and actuates the front active stabilizer in a direction to lift up the second side.

In a method for stabilizing the driving behavior of a tractor-trailer combination, a tilting inclination variable is obtained and a tilting limit is determined on the basis of the tilting inclination variable and is prescribed to a vehicle movement dynamics control system. A vehicle movement dynamics control device carries out the method. In order to improve the stabilization of the driving behavior of tractor-trailer combinations with different loads of the individual vehicles, the respective tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination, and the value of the tilting inclination variable for the determination of the tilting limit which is decisive for the determination of the tilting limit is obtained from the tilting inclination variables.

A controller is provided to, in response to a speed of the vehicle exceeding an allowable speed based on a measured grade while the vehicle is running and in neutral or park, actuating a vehicle holding mechanism to stop the vehicle.

A method for providing a clamping force that is generated with an automatic parking brake for a vehicle using a brake motor and a brake piston that acts upon a brake disk, includes building up a hydraulic pressure in a braking circuit of the vehicle after the automatic parking brake is applied. The method further includes determining a pressure loss gradient in the braking circuit of the vehicle. The method further includes performing or not performing a further application of the automatic parking brake based in part upon the determined pressure loss gradient.

A dissymmetric braking system has at least one right wheel braking device, at least one left wheel braking device, at least one device to apply a braking action, at least one actuating device to transform the braking action into a first pressure, at least one right wheel connection, at least one left wheel connection, and at least one pressure reducing device having at least one transfer device receiving the first pressure.
