CONTROLLER FOR A VEHICLE AND METHOD
A controller for a vehicle, a system, a vehicle, a method, a computer program and a non-transitory computer-readable storage medium are disclosed. The controller is configured to receive an indication of a measured speed of the vehicle, and determine whether a gradient on which the vehicle is located is below a threshold gradient. The controller is also configured to provide an output signal to cause a brake of the vehicle to be automatically applied to hold the vehicle stationary, in dependence on: the received indication of the measured speed of the vehicle being below a threshold speed; and the determination that the gradient is below the threshold gradient.
Method for maneuvering a motor vehicle with movement of the motor vehicle into a detection position, driver assistance system and motor vehicle
The invention relates to a method for maneuvering a motor vehicle (1), in which the motor vehicle (1) is manoeuvred within a determined driving tube (15), during the maneuvering a position of at least one object (8, 9) in a surrounding area (7) of the motor vehicle (1) is continuously determined by means of a control unit (3) on the basis of sensor data of at least one sensor (4) of the motor vehicle (1), which sensor (4) has a predetermined detection range (10), and if the at least one object (8, 9) is located outside the detection range (10) of the at least one sensor (4), the position of the at least one object (8, 9) is estimated, wherein a sensing position is determined by means of the control unit (3), and the motor vehicle (1) is moved to the sensing position if the at least one object (8, 9) is located outside the detection range (10), wherein the sensing position is determined in such a way that the estimated position of the at least one object (8, 9) is located within the detection range (10) if the motor vehicle (1) is located at the sensing position.
Driving assistance apparatus and driving assistance method
A driving assistance apparatus operates a collision avoidance apparatus that is mounted in a vehicle based on a distance to an object that is positioned ahead of the vehicle in a travelling direction. The driving assistance apparatus includes: a resistance determining unit that determines whether or not running resistance that suppresses rolling of wheels forward in the travelling direction of the vehicle is present; an operation determining unit that determines whether or not an accelerator operation by a driver of the vehicle is being performed; and a distance setting unit that sets an operation distance that is a distance at which the collision avoidance apparatus is operated. When the resistance determining unit determines that the running resistance is present and when the operation determining unit determines that the accelerator operation is being performed, the distance setting unit sets the operation distance to a value that is less than that when the running resistance is not present.
Automatic vehicle speed control system
An automatic vehicle speed control system for use in a vehicle having an implement is disclosed. The automatic vehicle speed control system includes: a controller configured to: set a speed of the vehicle to a creep setting; monitor one or more operating conditions of the implement; and automatically adjust the speed of the vehicle based on the one or more operating conditions of the implement.
Method for operating a motor vehicle and motor vehicle
A method for operating a motor vehicle including a traction electric motor, wherein the traction electric motor can be actuated for producing a creep torque that brings about a slow movement of the motor vehicle, wherein a plurality of creep torques of different magnitude can be set by a user of the motor vehicle.
ONE-PEDAL DRIVE SYSTEM FOR A VEHICLE
A vehicle includes an accelerator pedal, a brake pedal, an electric machine, friction brakes, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle during regenerative braking. The friction brakes are configured to brake the vehicle. The controller is programmed to, responsive to an operator selection of a one-pedal drive mode, decrease vehicle speed via regenerative braking in response to releasing the accelerator pedal. The controller is further programmed to transition the vehicle to an inhibit state in which the friction brakes are applied to prevent vehicle creep in response to receiving an automated signal to disable the one-pedal drive mode and vehicle speed becoming zero while the one-pedal drive mode is selected.
Methods and system for managing wheel creep torque of a vehicle
Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, electric machine torque is adjusted according to a wheel torque in a wheel torque creep mode where an engine provides torque to vehicle wheels. Operating the electric machine in this way may allow the electric machine to emulate wheel creep torque that is generated via an engine.
CONTROL DEVICE, VEHICLE, COMPUTER PROGRAM, COMPUTER READABLE MEDIUM AND METHOD FOR PERFORMING A GEARSHIFT DURING CREEP MODE
A method for, during creep mode, performing gearshift in a vehicle powertrain comprising a combustion engine, a gearbox, and a clutch is provided. The method comprises, in response to a request for gearshift, disconnecting the combustion engine from the gearbox by opening the clutch. The method further comprises, when the combustion engine is disconnected from the gearbox, shifting the gearbox and controlling the speed of the combustion engine to a target speed. Said target speed constitutes a combustion engine speed corresponding a desired combustion engine torque for completing a torque ramp during closing of the clutch. The method further comprises connecting the combustion engine to the gearbox by closing the clutch. A control device configured to perform the method and a vehicle comprising the control device are also provided.
Inching System for a Construction Vehicle
An inching system for a vehicle having a hydrostatic transmission and an engine that drives the transmission. The transmission has a pilot pressure port with a pressure of hydraulic fluid at the pilot pressure port controlling a level of power from the transmission, a beginning of draining of the hydraulic fluid from the pilot pressure port defining an inching starting point. The system includes a brake pedal and an electrohydraulic valve coupled to the pilot pressure port of the transmission, the valve being configured to drain the hydraulic fluid at the pilot pressure port. A sensor is coupled to the pedal to detect an input from the operator, the sensor producing a signal indicative of the input from the operator. A controller receives the signal and a speed of the engine. The controller controls the electrohydraulic valve dependent upon the signal and the engine speed so that the inching starting point is unchanged regardless of the speed of the engine.
CONTROLLER AND METHOD OF CONTROLLING SPEED OF A VEHICLE
A controller (201) for a vehicle (100), a system (200), a vehicle (100), a method (600), a computer program (204) and a non-transitory computer-readable storage medium (203) are disclosed. The controller (201) comprises means to receive an indication of a user selected direction of travel and an indication of the direction of motion of the vehicle (100). The controller (201) is configured to determine a proposed torque value in dependence on the direction of motion being an opposite direction to the selected direction of travel. The controller (201) also includes means to provide an output signal (403) configured to cause a motor (102) to apply torque, in dependence on the proposed torque value, to oppose motion in the opposite direction.
