A control system for a vehicle includes a speed sensor that generates a vehicle speed signal. A sway detection sensor generates an oscillation signal. A brake control is coupled to a vehicle brake and is associated with a trailer brake. A controller is coupled to a stability control system and brakes one or more of the vehicle brake and the trailer brake and in response to the oscillation signal.

Disclosed is a vehicle attitude control system for controlling the attitude of a vehicle in which a road wheel suspension is configured such that a roll axis of a vehicle body inclines downwardly in a forward direction. The vehicle attitude control system includes: a lateral acceleration sensor operable to detect a lateral acceleration; a brake actuator operable to apply a braking force; and a brake control device operable, based on a traveling state of the vehicle, to generate the braking force, wherein the brake control device is configured to execute vehicle attitude control of applying, to an inner rear road wheel, a larger braking force when the lateral acceleration of the vehicle is relatively large than when the lateral acceleration is relatively small, thereby suppressing uplift of an inner rear portion of the vehicle body.

The embodiments of the present application disclose a stability control system and a stability control method for a four-wheel drive electric vehicle and the four-wheel drive electric vehicle. In the stability control system, when the lateral acceleration is equal to or greater than an acceleration threshold, at least one of a first braking force signal, a second braking force signal, a first logic signal and a second logic signal is obtained. When the first logic signal is obtained, the body of the electric vehicle is controlled to keep stable. When the first braking force signal and the second logic signal are obtained, a motor is controlled to apply braking force to an outside front wheel. When the second braking force signal and the second logic signal are obtained, motors are controlled to apply braking force to the outside front wheel and an inside rear wheel.

Some embodiments are directed to a controller is provided for use with a vehicle braking system. The braking system can include brake assemblies coupled to an actuator. The controller can be configured to: receive data indicative of a requested braking force; select a distance of travel and actuating force for the actuator from respective predetermined ranges of values that are based on a curve determined using discrete portions representing constant incremental area under the curve for constant workload; and signal the brake assemblies to output braking response based on the selected distance of travel and actuating force of the actuator.

The present invention relates to a vehicle braking arrangement for a vehicle with wheels contacting the ground during normal running. The vehicle braking arrangement includes an emergency brake control unit, a first emergency braking system including non-reversible braking means arranged to operate independently of the vehicle wheels, at least one acceleration detector, and a wheel brake anti-locking system. The emergency brake control unit is arranged to input acceleration data (a) when the wheel brake anti-locking system is active, and to calculate the coefficient of friction () between the wheels and the ground. The emergency brake control unit is arranged to determine if the first emergency braking system should be activated in dependence of a first plurality of parameters, where one of these parameters is the coefficient of friction ().

A method for operating a brake system in a motor vehicle, having at least one hydraulic circuit that has a hydraulic pump and at least two wheel brakes, at least one actuatable inlet valve being allocated to each wheel brake. The brake system is monitored for a driver's braking request. To acquire the driver's braking request, a first wheel behavior of at least one wheel allocated to one of the wheel brakes is acquired, such that, upon acquiring of an unexpected wheel behavior, the braking intervention is interrupted and a second wheel behavior of the wheel is acquired and compared to the first wheel behavior of the wheel, and the driver's braking request is recognized as a function of the comparison.

A system for controlling a locking module for a vehicle door having an electronic latch mechanism is provided. An electronic handle switch is operatively connected to the door and a controller. The electronic handle switch is configured to at least partially control operation of the electronic latch mechanism. The locking module is configured to block the electronic handle switch, thereby preventing the door from being unlatched. The locking module is enabled when one or more predefined operating parameters are met. The controller disables the locking module when one or more entry conditions are satisfied. At least one sensor is operatively connected to the controller, the sensor being configured to indicate one of two states, a first state and a second state. The entry conditions include at least one sensor indicating the second state.
