BRAKING SYSTEM FOR AN AUTONOMOUS VEHICLE
A braking system in an at least partially autonomous vehicle, having one vehicle wheel brake per vehicle wheel and having a primary brake regulation system and a redundant secondary brake regulation system. One hydraulic actuator for actuating the vehicle brake is provided per vehicle wheel in a first vehicle axle which actuator is assigned to both the primary brake regulation system and also the secondary brake regulation system. One electromechanical primary actuator per vehicle wheel is assigned to the primary brake regulation system in the second vehicle axle and one electromechanical secondary actuator is assigned to the secondary brake regulation system.
METHOD AND CONTROL DEVICE FOR SETTING A WORKING POINT OF A SLIP CONTROLLER FOR A WHEEL OF A VEHICLE
A method for setting a working point of a slip controller for a wheel of a vehicle. Upon activating the slip controller, a torque at the wheel is controlled on the basis of the working point using a slip at the wheel, wherein the torque is monitored and a value of the working point is set to a previous value of the torque if the slip satisfies a condition.
BRAKE FOR VEHICLE AND CONTROL METHOD THEREFOR
The present disclosure provides a vehicle brake comprising: a reservoir configured to store a fluid therein; a hydraulic circuit configured to transfer a hydraulic pressure to a wheel of a vehicle; a plurality of valves disposed to regulate a flow of the fluid in the hydraulic circuit; and a master cylinder including a cylinder body, a main piston which is movably disposed within the cylinder body and in which a receptacle is formed at one side thereof, and a center piston which is disposed within the cylinder body and in which a penetration hole is formed in at least a part thereof, wherein the penetration hole is formed to have a size smaller than a cross-sectional area of the receptacle, and as the main piston moves, at least a part of the center piston is inserted into the receptacle, and thus a pressurizing area of the main piston decreases.
Braking control device
A braking control device includes a first control unit configured to execute first control for reducing a target braking force, which is either a front-wheel braking force to be applied to front wheels of a vehicle or a rear-wheel braking force to be applied to rear wheels during increasing of deceleration of the vehicle, in a case that a behavior of the vehicle is unstable as the target braking force is increased; and a second control unit configured to execute second control for reducing a rate of increase in the target braking force and increasing a rate of increase in the front-wheel braking force or the rear-wheel braking force, which is not the target braking force, prior to execution of the first control.
Sensor assembly for a vehicle and multi-circuit braking system
A sensor assembly for a vehicle includes control devices having respective evaluation and control units, and sensor elements assigned to a respective brakeable wheel and one of the ECUs and record a physical variable of the associated wheel and output same as an output signal to the associated ECU. The control devices execute a brake function based on the recorded physical variables. A respective sensor element is arranged on the brakeable wheels of a first axle. The output signals thereof are output to different ECUs of a single control device. Two respective sensor elements are arranged on brakeable wheels of a second axle. The output signals thereof are output to other ECUs in different control devices. The ECUs of the first axle output the respective received output signal to an ECU of another control device, such that each control device receives the corresponding recorded physical variable from all wheels.
METHOD FOR OPERATING A BRAKE SYSTEM FOR A MOTOR VEHICLE, CONTROL UNIT AND BRAKE SYSTEM
A method is provided for operating a brake system for a motor vehicle having at least one electric drive and having four wheels. The brake system has a brake device with a hydraulic pressure-generating unit and with a control unit, has a slip control system, and has four brake actuators which are connected in 1-channel configuration to the pressure-generating unit and which are assigned to a respective one of the wheels. In the event of a failure of the slip control system, in order to substitute the failed slip control system, the method has the following steps: a) applying a pressure to the four brake actuators by the pressure-generating unit, and b) driving the rear wheels by the electric drive.
Also provided are a control unit for carrying out such a method and a brake system having such a control unit.
BRAKE SYSTEM FOR A VEHICLE AND METHOD FOR BRAKING
The present invention relates to a brake system for a vehicle and a method for braking. The brake system includes a control module and an electromechanical brake that provides braking force to a wheel. The control module receives rotation speed information of at least one drive motor, which provides a driving torque to the vehicle, and wheel speed sensor information of at least one wheel, and compares the refresh rate of the rotation speed information of the drive motor and that of the wheel speed sensor information of the wheel, such that a wheel rotational speed generated from the information of a higher refresh rate will be used. The brake system provided by the present invention can obtain a more accurate wheel speed, thereby improving the control of the vehicle.
Method for securing a vehicle
The disclosure relates to a method for securing a vehicle, preferably a commercial vehicle, in an emergency braking situation, wherein the vehicle has a vehicle bus system and a braking system, the method having the following steps: monitoring signals on the vehicle bus system; detecting an emergency brake signal provided by a driver assistance system on the vehicle bus system; ascertaining whether the vehicle is at a standstill; bringing a braking device of the braking system into a braking position if a standstill of the vehicle is ascertained. The disclosure also relates to a control unit for a vehicle, a computer program, a braking system for a vehicle, and a vehicle.
REDUNDANT VEHICLE CONTROL SYSTEMS BASED ON TIRE SENSORS
A motion control system for controlling one or more torque generating devices on a heavy-duty vehicle, the system comprising a primary sensor system with a primary sensor control unit configured to interpret an output signal of the primary sensor system, one or more tire sensor devices mounted on, in, or in connection to, one or more tires of the heavy-duty vehicle, and a tire sensor control unit configured to interpret an output signal of the one or more tire sensor devices, wherein the motion control system is arranged to base motion control of the heavy-duty vehicle on output data of the tire sensor control unit in case of malfunction in the primary sensor system and/or in the primary sensor control unit, and on output data of the primary sensor control unit otherwise.
Method for activation and deactivation of a control device
In a method for activating and deactivating a control unit which can be used to control an electrically activatable assembly, the control unit is switched between a waking state, a sleep state and a deactivated state, wherein in the sleep state, the control device is disabled but can be transferred into the waking state by means of a sensor signal.
