CONTROL APPARATUS AND CONTROL METHOD
A control apparatus for controlling a vehicle includes a travel controlling unit for executing a one-pedal function for controlling both a driving force and a braking force of the vehicle according to an operation amount of an accelerator pedal, and an output controlling unit capable of displaying, on a display device of the vehicle, a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that a stopped state of the vehicle is being held by a braking force of the one-pedal function.
Emergency brake control method and device, ECU and vehicle
Disclosed are an emergency brake control method, device, ECU and vehicle. The method includes: when receiving a first trigger signal indicating that a vehicle enters a driving accompanying mode, activating the driving accompanying mode; and in the driving accompanying mode, when receiving an emergency brake command, controlling an Electronic Stability Program ESP to decelerate the vehicle at a preset deceleration in the driving accompanying mode, and sending a fuel cut-off request signal to an Engine Management System EMS to cut off a torque output of an engine.
Techniques for monitoring mechanisms to secure vehicle and remedial action
Systems and methods for controlling a park pawl system of a hybrid vehicle having a hybrid powertrain comprising an engine and a hybrid transmission comprising at least one electric propulsion motor, the systems and methods each utilizing a control system configured to detect, using a main control system portion, a desired park state based on at least an input via a transmission gear selector and an input via a brake pedal and detect, using a distinct monitoring system portion, whether the desired park state is valid based on at least the transmission gear selector and brake pedal inputs. When the desired park state is valid, the control system commands the park pawl system to the desired park state. When the desired park state is invalid, however, the control system commands an electric park brake of the vehicle to prevent movement at a driveline of the vehicle.
EMERGENCY BRAKE CONTROL METHOD AND DEVICE, ECU AND VEHICLE
Disclosed are an emergency brake control method, device, ECU and vehicle. The method includes: when receiving a first trigger signal indicating that a vehicle enters a driving accompanying mode, activating the driving accompanying mode; and in the driving accompanying mode, when receiving an emergency brake command, controlling an Electronic Stability Program ESP to decelerate the vehicle at a preset deceleration in the driving accompanying mode, and sending a fuel cut-off request signal to an Engine Management System EMS to cut off a torque output of an engine.
Techniques for detecting and monitoring unintended powertrain propulsive torque in hybrid vehicles
A control system and method for a hybrid vehicle involve controlling a hybrid powertrain comprising an engine and a transmission having one or more electric motors and not comprising a decoupling mechanism therebetween, detecting an operating condition where the transmission is in neutral and the vehicle is moving at a speed less than a low speed threshold, and in response to detecting the operating condition: determining a desired propulsive torque of the powertrain, determining an actual propulsive torque at the driveline, calculating a torque difference between the actual and desired propulsive torques over a period, comparing the calculated torque difference to a first movement threshold, and when the calculated torque difference exceeds the first movement threshold, applying an electric parking brake (EPB) of the vehicle.
Method and control system for charging a hybrid vehicle
A hybrid vehicle comprising an internal combustion engine, a hybrid system, a parking brake, a gear box and an electronic control system is provided. A method for controlling the method comprises charging the hybrid vehicle by receiving and storing electric energy, which enables a safe way of starting the internal combustion engine during the charging. An electronic control system is configured to: detect a starting attempt of the internal combustion engine during the receiving and storing of electrical energy; ensure that the hybrid vehicle is ready for a start of the internal combustion engine, which includes ensuring that the gear box is in a neutral gear and that the parking brake is applied; and thereafter start the internal combustion engine during the receiving and storing of electrical energy.
VEHICLE AND METHOD FOR CONTROLLING THE SAME
A vehicle includes a motor; a transmission; a battery; a mode input device for receiving a driving mode; a control information input device for receiving regenerative braking control information or gearshift level control information; and a controller configured to control at least one of braking torque of the motor and gearshift level of the transmission to control an amount of regenerative braking during regenerative braking by recognizing a signal received from the control information input device as a signal corresponding to the regenerative braking control information when the driving mode input to the mode input device is a first mode, and control the transmission to control the gearshift level of the transmission by recognizing a signal received from the control information input device as a signal corresponding to the gearshift level control information when the driving mode input to the mode input device is a second mode.
Vehicle control device
A vehicle control device (a control unit 100) includes a neutral control unit (100b), a brake hold control unit (100c), and a switching control unit (100d) configured to switch, when a predetermined switching condition is satisfied during execution of brake hold control by the brake hold control unit (100c), application of braking force to at least a drive wheel by execution of the brake hold control to application of the braking force to at least some vehicle wheels by an electric parking brake device. The neutral control unit (100b) stops execution of neutral control upon switching by the switching control unit (100d).
Automatic brake hold release directly to vehicle creep
A transportation vehicle provides a brake autohold function to maintain braking without requiring the driver to continuously apply pressure on a brake pedal. The vehicle comprises an autohold selector, a parking brake selector, a brake pedal, and an accelerator pedal. A braking system is adapted to enter an autohold event according to a pressed brake pedal at vehicle standstill during an active autohold mode toggled by the autohold selector. A controller is configured to terminate the autohold event in response to either a deactivation command using the parking brake selector or accelerator pedal movement, without deactivating the autohold mode. By manually terminating the brake autohold event the vehicle can begin to creep forward using only the torque generated by the engine at idle, thereby avoiding the additional torque that is generated when the accelerator pedal is used to terminate the brake autohold event.
Method for controlling a parking mode of a vehicle
A method for controlling a parking mode for a vehicle includes detecting an activation action of a user of the vehicle, determining a movement status of the vehicle, and activating a parking mode for the vehicle by closing a parking brake of a brake device of the vehicle and by engaging a gearshift lock of a transmission of the vehicle.
