Provided are a vehicle body behavior control device which can reduce unstable behavior of a vehicle body and a method of controlling behavior of a vehicle body which can reduce unstable behavior of the vehicle body. A vehicle body behavior control device incorporated into a vehicle body having a plurality of wheels includes: a behavior control mechanism which controls behavior of the vehicle body; and a control part which controls an operation of the behavior control mechanism based on an axle load applied to the wheel calculated using a gradient value of a road surface.

A brake system includes a brake activator which first activates a central rear brake and lastly activates a front brake of a right front brake and a left front brake which is provided on a front wheel which is an inner wheel by operating an input member. When an operation amount of the input member from an initial state to a maximum operated state thereof is divided equally into three portions which are defined as a low braking force area, a middle braking force area, and a high braking force area, the brake activator activates the central rear brake, the right front brake, and the left front brake to operate in the low braking force area.

A method for detecting a slope of a road on which a vehicle is traveling in at least one spatial direction. The vehicle has a body and a chassis with a plurality of wheels. An inclination of the vehicle body in the spatial direction is determined. For at least one wheel, a vertical distance to the vehicle body is detected. The distance so determined is used to calculate an inclination of the chassis in the spatial direction. The slope of the road in the spatial direction is determined from a difference between the inclination of the vehicle body in the spatial direction and the inclination of the chassis in the spatial direction.

A physical quantity sensor includes: a base; wiring disposed in the base; a support that includes a first bonded surface bonded to the base and a second bonded surface bonded to the wiring; a suspension beam connected to the support; and an electrode finger supported by the suspension beam. The support is located between the first bonded surface and the suspension beam and includes a first overhang separated from the base.

The disclosure relates to a method for operating at least one parking brake of a motor vehicle, which parking brake can be activated and deactivated in an automated manner, wherein, for the purpose of automated operation of the parking brake, state values of the motor vehicle are monitored and compared with prespecifiable conditions, and wherein the parking brake is activated when a first group of the conditions is met and is deactivated when a second group of the conditions is met. It is provided that the parking brake is activated only when all of the conditions of the second group can be successfully checked for compliance or non-compliance with the respective condition.

A method for operating a hydraulic brake system of a motor vehicle includes enabling a parking brake function by actuating a pressure generator and an actuator such that the pressure generator and the actuator together generate a total clamping force at a wheel brake, and actuating the pressure generator based on a movement of an actuator element and/or a brake piston, the movement generated by the actuator. The brake system includes the wheel brake having the brake piston, a brake pedal device, the pressure generator configured to actuate the wheel brake, the actuator assigned to the wheel brake and having the actuator element configured to actuate the wheel brake. A force that displaces the brake piston in order to actuate the wheel brake is generated by the pressure generator and/or the actuator.

A controller determines a load weight associated with a plurality of pneumatically independent circuits of a vehicle suspension system. The controller is adapted to receive an electronic pressure signal, at a controller electronic input port, based on a single pneumatic signal representative of respective pneumatic pressures in the plurality of pneumatically independent circuits. The controller is also adapted to determine the load weight based on the electronic pressure signal and control an operation of a function of an associated vehicle based on the load weight.

In a method for warning a vehicle driver of a risk of the vehicle overturning about its longitudinal axis, a control device detects the current transverse acceleration of the vehicle and emits a warning signal based thereon when a risk of overturning is presented. The warning signal is dependent upon at least one transverse acceleration value, which is critical for overturning, detected by the control device while the vehicle is being driven, and a measurement of the transverse acceleration of the vehicle at which the vehicle would actually overturn about its longitudinal axis. The transverse acceleration value that is critical for overturning is determined automatically based on the vehicle behavior exhibited during driving on a curve.

A vehicle control device, method, and a vehicle control program capable of controlling a vehicle with good responsiveness. The vehicle control device includes: a surrounding situation recognizer configured to recognize a situation in an advancing direction of a vehicle; and an automatic brake controller configured to cause a brake device to apply a brake force in accordance with the situation in the advancing direction of the vehicle recognized by the surrounding situation recognizer and is configured to cause the brake device to release the brake force at a time of accelerating the vehicle, in which when the vehicle is decelerating, the automatic brake controller configured cause a brake device to release the brake force in response to an increase in vehicle speed of the vehicle when the vehicle is subject to acceleration control or an acceleration operation before stopping.
