BRAKING SYSTEM FOR A VEHICLE
Methods, devices, and systems for communicating a brake pedal input to a brake without a physical connection through a firewall of a vehicle is provided. The position of the pedal is detected and electronically communicated to a control unit that causes the brake to slow the rotation of a wheel and inhibit the movement of a vehicle. In addition, the driver can select a pedal force profile to provide a preferred pedal feel for the driver. The brake system and the control unit can also compensate for additional loads in or attached to the vehicle such as a trailer. For example, the control unit cases the brake to activate with an increased force so the vehicle slows at the same rate and with the same pedal feel for the driver, even with an additional load. Further features and details are described herein.
Devices, systems, and methods for vehicle braking
Systems and methods are described for coordinating and controlling vehicles, for example heavy trucks, to follow closely to behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicle sensors to monitor and control, for example, gross vehicle weight, axle loads, and stopping distance. In some aspects, two vehicles can determine information associated with their gross weight and axle load, and apply that information to assist with determining a bounding box indicating which vehicle will take longer to stop. Based on which vehicle will take longer to stop, an order of vehicles in a potential platoon is determined.
DEVICE AND METHOD FOR DECELERATING A VEHICLE HAVING A FRONT-LOADING DEVICE
A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.
WORK MACHINE SPEED CONTROL BRAKING
A machine includes an engine, a brake system, a speed sensor, a grade sensor, a load sensor, and a controller in electrical communication with the engine, the brake system, the one or more retarding systems, the speed sensor, the grade sensor, and the load sensor. The controller is configured to: determine a grade force based on the weight of the machine and the grade at which the machine is disposed; determine a deceleration force based on a target deceleration and the weight of the machine; monitor the speed at which the machine is traveling; determine an actual deceleration of the machine based on the monitored speed at which the machine is traveling; determine a deceleration error based on a difference between the actual deceleration and the target deceleration; determine a force correction based on the deceleration error; and control the brake system to apply a total brake force equal to the sum of the grade force, the deceleration force, and the force correction.
BRAKE CONTROL TECHNIQUE TO STOP A VEHICLE FOR ASSISTING AUTOMATIC TRAILER HITCHING
A vehicle control system configured to control a braking operation of a hitch ball to a coupler on a trailer. The system may comprise a vehicle brake control system, a maneuvering system, an image sensor configured to capture an image data, and a velocity sensor. The system may also comprise a vehicle mass sensor configured to detect a vehicle mass and a controller. The controller may be configured to control the maneuvering system of the vehicle along a vehicle path. The controller may also identify a coupler distance based on the image data depicting a coupler of the trailer. The controller may also calculate a stopping distance for the braking operation based on a plurality of braking parameters, wherein the braking parameters comprise the velocity, the break pressure, and the vehicle mass.

The present disclosure relates to a method for autonomously controlling a vehicle performed by a vehicle control system, the vehicle control system comprising a zone control system, a collision prediction system and a braking control system, the method comprising the steps of: defining in the zone control system at least a first zone and a second zone relative to a vehicle position, predicting a collision with an obstacle with the prediction system, autonomously braking the vehicle with the braking control system in a first braking mode if the collision is predicted to occur in the first zone and braking the vehicle with the braking control system in a second braking mode if the collision is predicted to occur in the second zone.
Driving adjustment for vehicle loading
A computer includes a processor and a memory storing instructions executable by the processor to determine at least one of a vehicle pitch or a longitudinal center of gravity from data measured while deactivating a first brake for a first axle and applying a second brake for a second axle, and operate the vehicle based on the at least one of vehicle pitch or longitudinal center of gravity. The instructions may further include to determine a vehicle weight from the data, and operate the vehicle based on the vehicle weight.
Ascertaining an offset of an inertial sensor
A method of providing an additive offset of a longitudinal acceleration signal of a traveling motor vehicle. The signal being measured by an inertial sensor is ascertained. At least the longitudinal acceleration signal, a braking signal, and a drive signal are detected. A force balance of the longitudinal dynamic of the motor vehicle is analyzed. The signals are detected both during at least one acceleration process as well as during at least one braking process. The signals during the acceleration processes are detected and/or analyzed separately from the signals during the braking processes, and the additive offset is ascertained by comparing the signals detected during the acceleration processes or the values calculated therefrom with the signals detected during the braking processes or the values calculated therefrom. The invention further relates to an electronic controller.
Vehicle Brake Health Monitoring
There is disclosed a method and system for vehicle brake management. A vehicle brake test is performed in order to output a measure of brake performance under one or more test condition. The measure of brake performance is used to generate a value of current vehicle brake effectiveness for a predetermined usage condition. A mathematical model is applied to said value of current vehicle brake effectiveness so as to predict a decline in braking effectiveness with vehicle usage. The mathematical model is used to determine a point at which said predicted decline crosses a threshold value of vehicle brake effectiveness and an indication of the extent of vehicle usage corresponding to said crossing point is output. The method and system may be used to monitor brake performance compliance with regulations and/or to generate brake test/maintenance schedules.

A service and emergency braking control system for at least one railway vehicle, including a plurality of braking control modules is provided. Each braking control module is equipped for: if, when achieving a determined braking torque value from an applied braking torque, an instantaneous deceleration value is lower than the target deceleration value, increasing the applied braking torque until the instantaneous deceleration value reaches the target deceleration value, or until the maximum available adhesion from an axle controlled by said braking control module is indicated.
