Anti-jerk control method for electric vehicle
An anti-jerk control method for an electric vehicle incorporates an anti-jerk function that can be performed more accurately and effectively by utilizing a real-time weight change of an electric vehicle. The anti-jerk control method includes: estimating vehicle weight by a controller based on vehicle driving information collected from a vehicle; determining a required torque command of a driver by the controller based on the vehicle driving information collected from the vehicle; determining anti-jerk torque according to the vehicle weight based on calculated speed deviation and the estimated vehicle weight information; and controlling a drive motor according to a compensated motor torque command by compensating the required torque command with the anti-jerk torque in the controller.
SYSTEM AND METHOD FOR RESTARTING AN ENGINE
Systems and methods for operating a hybrid vehicle are presented. In one example, an integrated starter/generator (ISG) is operated in a speed control mode after an engine stop request. The ISG is prevented from stopping while engine rotational speed is greater than a threshold engine rotational speed so that the engine may be restarted via the ISG.
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.
Vehicle control method and vehicle control apparatus
At the time of starting a vehicle, if the vehicle is stopped even without an operation of braking the vehicle, a drive force to be generated before an actual start of the vehicle is limited to or below a predetermined maximum drive force.
Control system for a vehicle
The present disclosure relates to a creep speed control system for a vehicle having at least one electric motor for providing torque to at least one vehicle wheel. The system comprises an input configured to receive a current speed signal indicative of a current speed of the vehicle; a creep speed control module that is configured to activate when the current speed of the vehicle crosses a predetermined threshold above a creep speed target value; and, an output configured to, upon activation of the creep speed control module, send a creep speed control torque signal to the at least one electric motor to control the vehicle speed in dependence on the creep speed target value, wherein the creep speed control torque signal is limited to a creep speed control filtered torque value less than a creep speed control maximum torque value.
Driving assistance apparatus
A driving assistance apparatus includes a clutch provided between a drive source and a transmission, a clutch operator with which a driver who drives a vehicle disengages the clutch, a clutch operation detector that detects that the clutch is disengaged, a shift operator with which the driver sets the transmission at least to a neutral position, a shift position detector that detects that the transmission is in the neutral position, a low-speed motor, and a controller that controls a drive force of the low-speed motor. The controller includes a driving mode setter that sets a driving mode of the vehicle to a motor driving mode when the clutch is detected to be disengaged or the transmission is detected to be in the neutral position. The controller stops the drive source and starts the low-speed motor when the driving mode is set to the motor driving mode.
CREEP TORQUE CONTROL SYSTEM FOR A VEHICLE
Aspects of the present invention relate to a control system for a vehicle. The control system comprises one or more controllers, and is configured to select a relationship between torque and speed based, at least in part, on a determined terrain mode. The control system is further configured to control a drive torque of the vehicle in accordance with the selected relationship between torque and speed when the vehicle is operating in a creep control mode. The vehicle may be a hybrid or electric vehicle and the terrain mode may be determined from a Terrain Response™ switch input or automatically determined.
ELECTRIFIED VEHICLE ONE PEDAL DRIVE TRANSITION CONTROL
An electrified vehicle may include an electric motor coupled to a battery to propel and brake the vehicle, a pedal generating a pedal position signal including a released position signal, friction brakes configured to provide a stopping force to vehicle wheels, and a controller programmed to control the motor and the brakes in response to the pedal being released to decelerate the vehicle to a stop, and to control the motor and an engine (in hybrid vehicles) to inhibit propulsive torque to the wheels after stopping due to the pedal released position until receiving driver input indicative of a request for moving the vehicle, such as depressing the brake or accelerator pedal, or activating an automated vehicle maneuver, such as a parking maneuver, cruise control, or stop-and-go control. Inhibiting torque may include inhibiting creep torque and/or operating the electric machine to charge the battery when the engine is running.
METHOD OF CONTROLLING TOWING MODE OF VEHICLE
The present disclosure provides a method of controlling a towing mode of an vehicle, which may easily charge a battery of a towed vehicle by allowing a motor of the towed vehicle to output a charging torque for charging the battery and allowing a motor of the towed vehicle to output a creep torque or a regenerative braking torque capable of charging the battery even upon deceleration traveling together with a compensation control of increasing engine output power of a towing vehicle compared to default output power upon acceleration and constant speed traveling by selecting one of an eco-towing mode, a power towing mode, and a target charging towing mode for charging the battery of the towed vehicle when the towing vehicle, which is a hybrid electric vehicle, tows the towed vehicle, which is an electric vehicle or a hybrid electric vehicle.
Methods and systems for start/stop
Methods and systems are provided for a start/stop feature. In one example, a method includes adjusting start/stop conditions in response to a vehicle operator customizing start/stop conditions. The vehicle operator customizes start/stop conditions for a plurality of different driving conditions.
