摘要:
An arrangement for controlling the activity of an actuator (AK) of a brake of a motor vehicle has a first path for a first signal (TRIG1) relating to the activity of the actuator (AK), a second path for a second signal (TRIG2) relating to the activity of the actuator (AK), and a circuit (MOSFET, TRANS, RES3, BAT2) enabling the actuator (AK) to be activated in such a manner that the actuator (AK) is activated if a determined modification of the first signal (TRIG1) and also a determined modification of the second signal (TRIG2) is present. The determined modification of the first signal (TRIG1) is in the opposite to the determined modification of the second signal (TRIG2).
摘要:
A control system for controlling a safety system of an automotive vehicle having a transmission and a differential. The system includes left and right wheel speed sensors associated with respective vehicle wheels and generating left and right wheel speed signals, and a transmission output shaft speed sensor generating a transmission output shaft speed signal. A controller is coupled to the wheel speed sensors and the transmission output speed sensor, and determines a reference wheel speed for one of the left or right wheels as a function of the other of the left or right wheel speed signal and the transmission output shaft speed signal. The controller controls the safety system in response to the determined reference wheel speed.

A control system for an electromechanical brake with self-reinforcement has a unit adapted to recognize brake failure, a unit adapted to detect the actual state of motion of the device to be braked, and a unit adapted to open and close the brake upon recognition of a failure dependent upon the detected actual state of motion of the device to be braked. The unit adapted to detect the state of motion detects in particular the rotational velocity of a brake disk assigned to the brake.

A vehicle includes a control system that is used to control a vehicle system. The control system determines a roll condition in response to a yaw rate sensor and a pitch rate sensor without having to use a roll rate sensor. A relative roll angle, relative pitch angle, global roll angle, and global pitch angle may also be determined. A safety system may be controlled in response to the roll condition, roll angle, or the pitch angles individually or in combination.

An electric brake system for an aircraft includes a power interlock mechanism that prevents inadvertent (uncommanded) application of brakes. The interlock removes operating power from the brake mechanisms whenever the brake system sensor data does not indicate a legitimate brake application condition. The interlock processing occurs in parallel with the brake command processing such that even if an inadvertent brake command is generated, the brake mechanisms will be unable to act upon the inadvertent brake command.

A vehicle control device for controlling the driving force and braking force that is applies to a vehicle to maintain a target wheel speed includes: a plurality of determination parts each of which determines the wheel speed of a corresponding one of a plurality of wheels of the vehicle; a calculation part that calculates the wheel speed validity threshold for each wheel based on the determined wheel speeds; a decision part that decides whether the wheel speed validity threshold calculated for each wheel is below a specific threshold speed; a setting part that resets the target wheel speed depending on the result of the decision by the decision part; and an estimation part that estimates the vehicle speed based on the determined wheel speeds.
摘要:
The invention relates to a method and device for monitoring brake signals in a vehicle with a gearbox control unit and engine control unit. An error recognition or a plausibility control of said brake signals is carried out. Brake light signals can be received by a gearbox control unit or an engine control unit. Brake light switch signals can be guided by a CAN bus. A cable break or defective contacts or a short-circuit can be considered as errors.

A brake control system for a vehicle, in particular a commercial vehicle, includes a service brake for braking the wheels of the vehicle. To increase operating safety, the service brake is equipped with an electronically actuatable brake unit for each wheel for actuating the brake of the respective wheel. Two redundantly connected central control devices are connected via control lines to the brake units so as to actuate the brake units independently of one another.
摘要:
A method and apparatus for carrying out a drive belt slippage regulation in a continuously variable transmission. A driving disk set and a driven disk set are connected together for torque transfer by an endless torque-transmitting element in which a power ratio between the driving disk set and the driven disk set of a variable speed drive is set as a function of a safety margin value.
摘要:
For monitoring of a measuring device (1), located in a wheeled vehicle, the measuring device (1) is configured so as to measure three linear accelerations (in unit 3) of the wheeled vehicle, which extend perpendicular to each other, respectively, as well as three rotational speeds (in unit 4) and one respective rotational movement or a component of a rotational movement about an axis of the wheeled vehicle, the three axes running perpendicular to each other, respectively. At least components of an orientation of the wheeled vehicle in a vehicle-external coordinate system are determined (in unit 7) from the three rotational speeds, and at least one of the measured linear accelerations is monitored (in unit 9) using at least the components of the orientation and a comparative variable (from unit 8).
