A system and method for brake pre-charging includes pre-filling brakes, based on proximity information from a forward-looking sensor, to reduce the initial delays associated with braking. By reducing the initial delay in converting driver brake pressure requests into actual brake torque to the wheels, the stopping distance required for braking is reduced.

A multipurpose sensing system (10) for a vehicle (12) includes an optic (14) that is directed at multiple viewing areas (18). A vision sensor (16) is coupled to the optic (14) and generates multiple object detection signals corresponding to the viewing areas (18). A controller (22) is coupled to the vision sensor (16) and generates multiple safety system signals in response to the object detection signals.

An adaptive cruise control (ACC) system (10) for a host vehicle (12) is provided. The ACC system (10) includes a forward-looking sensor (18) generating a range signal corresponding to a distance between the host vehicle (12) and a target vehicle. The forward-looking sensor (18) also generates a range rate signal corresponding to a rate that the distance between the host vehicle (12) and the target vehicle is changing. A controller (20) is electrically coupled to the forward-looking sensor (18). The controller (20) maintains a preset headway distance between the host vehicle (12) and the target vehicle, when the host vehicle velocity is less than about 40 KPH, by adjusting the host vehicle velocity in response to the range signal and the range rate signal. A method for performing the same is also provided.

A method and system for detecting a target obstacle in front of a vehicle traveling on a road includes a radar positioned at a center of the vehicle for transmitting radar waves ahead of the vehicle for use in determining a first position of the objects in front of the vehicle relative to the radar. A lane position measurement device determines a lateral deviation between the center of the vehicle and a lane boundary of the road. Control logic then determines a curvature of the road based on the lateral deviation, independent of the traveling path of the vehicle. The control logic then determines a second position of the objects based on the curvature of the road and the target obstacle based on the second position of the objects.

A roll stability control system (18) for an automotive vehicle (10) includes an external environment sensing system, such as a camera-based vision system, or a radar, lidar or sonar-based sensing system (43) that generates image, radar, lidar, and/or sonar-based signals. A controller (26) is coupled to the sensing system and generates dynamic vehicle characteristic signals in response to the image, radar, lidar, or sonar-based signals. The controller controls the rollover control system (18) in response to the dynamic vehicle control signal. The dynamic vehicle characteristics may include roll related angles, angular rates, and various vehicle velocities.

Methods of performing threat assessment of objects for a vehicle include detecting an object. Kinematics of the vehicle and of the object are determined. A brake threat number and a steering threat number are determined in response to the kinematics of the vehicle and the object. The threat posed by the object is determined in response to the brake threat number and the steering threat number.

A turn signal system includes at least one sensor detecting road markers and generating therefrom road marker signals. A turn signal deactivates in response to a control command generated by a controller. The controller receives the road marker signals, and determines at least one of whether the system is undergoing a turning condition or has completed the turning condition from the road marker signals. The controller generates the control command when the system has completed the turning condition. A redundancy system verifies the control command.
摘要:
An emergency brake assist apparatus amplifies driver braking force upon imminent contact detection. A brake pedal, operated by the driver, exerts a pedal force upon a variable brake booster. A braking system is coupled to the variable brake booster that produces a variable brake booster force causing the braking system to exert a braking force proportional to the pedal force during normal operation. When a forward detection apparatus detects an imminent contact, a controller signals the variable brake booster to increase the variable brake booster force such that the braking system exerts an amplified braking force proportional to the pedal force.
