Method for operating a motor vehicle having a start/stop system
A method for operating a motor vehicle having an internal combustion engine, a service brake, a brake booster, a parking brake, a wheel-speed sensor and an inclination sensor is disclosed. The method including measuring the speed of motor vehicle using the wheel-speed sensor to create a speed signal. An inclination of the motor vehicle with respect to the direction the motor vehicle is sensed and an angle signal is created. The internal combustion engine is started when the speed measured is greater than zero and the inclination of the motor vehicle is greater than a predetermined value, such that the internal combustion engine creates a partial vacuum to power the brake booster to assist with the operation of the service brake.
Valve system and method for controlling same
A valve system includes an isolation check valve delivering pneumatic fluid as a supply pressure, a double-check valve adapted to deliver a braking demand control signal of the pneumatic fluid based on a higher of a first braking demand in a first pneumatic braking circuit and a second braking demand in a second pneumatic braking circuit, and a control module. The control module is adapted to receive the supply pressure as a control module supply pressure of the pneumatic fluid, receive a control module control pressure of the pneumatic fluid based on the braking demand control signal, and deliver a control module delivery pressure of the pneumatic fluid based on the control module supply pressure and the control module control pressure. A tractor protection module delivers the pneumatic fluid at the control module delivery pressure based on a trailer park brake pressure of the pneumatic fluid.
Vehicle control apparatus and control method thereof
A vehicle control apparatus includes an input portion configured to receive an engagement operation signal; a determiner configured to determine whether the engagement operation signal is generated before a vehicle is stopped and whether a current state is a first state; when the current state is the first state, determine whether the current state is a second state in which the vehicle is intended to be stopped on flat land; and, when the current state is the second state, determine that the current state is a third state in which it is impossible for the EPB apparatus to determine an inclination; and a controller configured to turn off an inclination determining mode and turn on an inclination determination impossible mode of the EPB apparatus when the current state is determined as the first state, the second state, and the third state.
Method and device for operating a braking system of a motor vehicle, braking system
A method for operating a braking system of a motor vehicle with at least one hydraulically actuable wheel brake, a brake actuation device for hydraulically actuating the wheel brake, an electric brake booster for setting a predefinable hydraulic braking boost, and at least one parking brake assembly includes monitoring the motor vehicle to detect standstill and monitoring the parking brake assembly to detect activation thereof. The method further includes reducing a braking boost set by the brake booster if standstill of the motor vehicle has been detected and an activation of the parking brake assembly has been detected.
Customized electric parking brake response to maintain engine auto-stop with brake released
A vehicle control method includes, by a controller, while an engine is auto-stopped and an electric parking brake is engaged, auto-starting the engine without releasing the electric parking brake responsive to application of an accelerator pedal less than a predefined amount, and auto-starting the engine and releasing the electric parking brake responsive to application of the accelerator pedal greater than the predefined amount. The method also includes comprising auto-stopping the engine and engaging the electric parking brake responsive to vehicle speed being less than a predefined threshold speed.
Vehicle hill start assist system
A hill start assist system for a motor vehicle including a control system using sensor data from at least one sensor to provide the hill start assist with improved response behavior. The control system activating the hill start assist automatically and independently of whether the motor vehicle is on an upward incline depending on sensor data from the sensor indicating a local upward gradient in a driving surface in a region of a vehicle axle.
Method for operating an automated parking brake
A method for operating an automated parking brake in a motor vehicle, having a hydraulic actuator for producing a hydraulic force component and an electromechanical actuator for producing an electromechanical force component, includes superimposing the hydraulic force component and the electromechanical force component to obtain a total clamping force for a parking brake operation, and maintaining the total clamping force by self-locking of the parking brake. The method further comprises during the parking brake operation, setting at least one defined hydraulic pressure level using the hydraulic actuator, and locking-in a defined hydraulic pressure level with a valve when the at least one defined hydraulic pressure level is reached.
Method for operating an at least semi-automated mobile platform
A method for operating an at least semi-automated mobile platform which includes wheels, a braking system, and an acceleration sensor that generates acceleration values. The braking system, using a holding force, cooperates with the wheels in such a way that the platform is selectively fixed in a position. Each wheel includes a rotation angle sensor that generates a signal pulse based on a rotational position of the wheel. The method includes: reducing an initial holding force of the wheels, corresponding to an initial value of a control gradient; controlling the control gradient based on the acceleration values when the rotation angle sensor of a wheel has generated a first signal pulse; increasing the holding force of at least one of the wheels corresponding to a fixation gradient when the rotation angle sensor of a set of further wheels of the wheels has generated a signal pulse, to fix the platform.
