Abstract:
A vehicle brake control providing understeer correction through an increase in differential brake pressure favoring the inside wheel applies the increase, in the absence of anti-lock braking activity, across the rear wheels unless one or more sensors indicates a likely low traction condition on the inside rear wheel, in which case the increase is applied to the front pair of wheels. Preferred sensors include a suspension position sensor for the inside rear wheel or other sensor derived information from a suspension control system that indicates large body roll in a turn together with forward body pitch. In the absence of a suspension control system, preferred sensors include vehicle lateral and longitudinal accelerometers indicating vehicle roll and pitch together with a steer angle sensor indicating a significant turn. An indication could also be derived from a normal force sensor on the wheel or normal force information derived from other sensors such as a tire pressure sensor.
Abstract:
In a vehicle braking system with electronic brake distribution the threshold level of slip of the rear wheels is increased when the front brake temperature is estimated to have increased to a level where brake fade will occur. This allows more braking torque to be applied to the rear wheels to counteract the brake fade at the front wheels. This increase in threshold slip is, however, overridden if the vehicle is cornering, as detected by a lateral accelerometer or a wheel speed difference across the vehicle, to avoid a reduction in vehicle stability during cornering.
Abstract:
A method of controlling the brake system of a vehicle. The method includes receiving one or more electrical signals each indicative of a value of a respective vehicle-related parameter. The method further includes detecting that the vehicle is traveling across a slope based on the value(s) of one or more of the vehicle-related parameters. The method still further includes automatically modifying the amount of brake torque being applied to at least certain of the wheels of the vehicle in response to the detection of the vehicle traveling across a slope by increasing the amount of brake torque being applied to one or more wheels on one side of the vehicle, and decreasing the amount of brake torque being applied to one or more wheels on the other side of the vehicle.

Abstract:
The vehicle motion control device performs anti-lateral overturn control for increasing a brake force to be generated at a front inside wheel of a vehicle in order to cause skidding at the front inside wheel when a condition for increasing a brake force to be generated at an outside wheel is satisfied, wherein the condition is that the vehicle motion control device is in the anti-lateral overturn mode and the vehicle is turning.

In the motorcycle braking device according to the present invention, in a front and rear wheel interlocking brake control, an additional target pressure associated with a brake input pressure of one of a front wheel hydraulic circuit and a rear wheel hydraulic circuit is applied to another wheel driven by the front wheel hydraulic circuit or the rear wheel hydraulic circuit.
Abstract:
A control system (18) and method for an automotive vehicle (10) includes a roll rate sensor (34) for generating a roll rate signal, a lateral acceleration sensor (32) for generating a lateral acceleration signal, a longitudinal acceleration sensor (36) for generating a longitudinal acceleration signal, and a yaw rate sensor (28) for generating a yaw rate signal. A safety device or system (44) and the sensors are coupled to a controller. The controller (26) determines an added mass and the height of the added mass on the vehicle, or a roll gradient, a roll acceleration coefficient, and/or a roll rate parameter that take into account the added mass and height from the roll rate, the lateral acceleration, the longitudinal acceleration, and the yaw rate of the vehicle, and controls the safety system in response thereto.
