  • Publication number: 20050033499
    Abstract: The invention relates to a method for estimating road-to-tire friction between tires of a wheeled vehicle and a road surface, which vehicle is provided with a collision avoidance system. The method includes the steps of applying a positive torque to both wheels on a first axle and an equal and opposite negative torque to at least one wheel on a second axle. The method further includes measuring current values for vehicle speed, angular acceleration of the wheel on the second axle and the negative torque applied to said wheel. The method also includes determining a current friction coefficient using a friction coefficient determining device. The invention further relates to an apparatus for using the method.

  • Patent number: 6816764
    Abstract: A vehicle control system (10) including a vehicle motion control subsystem (12) that has an input receiving an intended driving demand (14) and a plurality of coordinator subsystems (16) for coordinating actuators of the vehicle. The vehicle motion control subsystem (12) communicates with the coordinator subsystems (16) to determine whether a single coordinator subsystem (16) can carry out the intended driving demand (14). The vehicle motion control subsystem (12) will distribute demand signals among one or more of the coordinator subsystems (16) to allow the vehicle to implement the intended driving demand (14).

  • Publication number: 20040148080
    Abstract: A steering system and control system for controlling an assist force imposed to the steering assembly of a vehicle, so as to deliver a steering wheel resist torque that can be felt by the vehicle driver and a method for the same, wherein the actual steering wheel resist torque is compared with a desired steering wheel resist torque, whereupon the actual steering wheel resist torque is adapted to be substantially the same as the desired steering wheel resist torque through adapting the amount of said assist force.

  • Patent number: 6659572
    Abstract: 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.

  • Patent number: 6655749
    Abstract: An enhanced emergency brake assist system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle after the driver fully releases the accelerator pedal. The braking force may be reduced when the driver or passenger are unbuckled.

  • Patent number: 6607255
    Abstract: A brake control system (10) for an automotive vehicle (12) is provided. The system (10) includes a vehicle sensor complex (16) that generates a vehicle sensor complex signal and an object detection system (14) that generates an object detection signal. A brake controller (22) is electrically coupled to the vehicle sensor complex and the object detection system. The controller (22) in response to the vehicle sensor complex signal and the object detection signal generates a brake ramping control signal. Controller (22) adjusts brake pressure in response to the brake ramping control signal. A method for performing the same is also provided.

  • Publication number: 20030055563
    Abstract: The present invention relates to a method for avoiding vehicle collisions and collision mitigation. The method comprises the steps of predicting the probability density function (11, 12, 13, 14) for the position of a vehicle at several future occasions and predicting the probability density function (21, 22, 23, 24) for at least one additional object at several future occasions. Further the method comprises the step of forming the joint probability density function for the relative positions of the vehicle and object at several future occasions and integrating over the area in which the vehicle and object are in physical conflict.

  • Patent number: 6523912
    Abstract: An autonomous emergency braking system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle while the vehicle engine speed is reduced. The amount of brake force applied is a continuous function of relative speed, relative distance, collision probability and target classification. The braking force may be reduced when the driver or passenger are unbuckled or may be disabled if the driver applies full throttle.

When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle while the vehicle engine speed is reduced. The amount of brake force applied is a continuous function of relative speed, relative distance, collision probability and target classification. The braking force may be reduced when the driver or passenger are unbuckled or may be disabled if the driver depresses the accelerator pedal by a predetermined amount. In addition, the amount of brake force applied by the driver is amplified to further enhance braking performance.
