A PM-ECU configured to control a drive torque of a vehicle is configured to be stopped in response to a driver's operation of a start switch and then activated in response to a driver's re-operation of the start switch. The PM-ECU is configured to be activated and place a restriction on the drive torque of the vehicle, in response to a re-operation of the start switch after the PM-ECU is stopped in response to an operation of the start switch. The PM-ECU is configured to remove the restriction on the drive torque in response to a reduction of an operation amount by which an accelerator pedal is operated.

A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.

A method for implementing and canceling an automatic operation of a body of a machine includes receiving a selection of an automatic setting according to a first operation of a hoist mode actuator, determining an activation state of the automatic setting, causing an automatic operation of an engine of the machine to adjust an idle level of the engine and an automatic operation of a hoist system to move the body in a first direction to a first position. The method includes canceling the automatic operation of the engine and the automatic operation of the hoist system and controlling the idle level of the engine according to operations of a throttle, the hoist system to move the body according to the idle level of the engine and respective directions of the second operation the hoist mode actuator and subsequent operations of the hoist mode actuator.

An automatic control apparatus for an engine detects an operation position of a mechanical shift lever for shifting gears of a transmission, automatically stops the engine when a predetermined condition is satisfied in the case where the operation position is at a first specific range, and automatically restarts the engine in the case where, after the operation position is switched from the first specific range to a second specific range while the engine is stopped, the second specific range is maintained for a pre-determined time. When the operation position is switched from the first specific range to the second specific range while the engine is stopped, it is determined whether or not the driver has an intention to start the vehicle, and if YES, the predetermined time is set to be shorter than when it is determined that there is no intention to start the vehicle.

An electrified fire fighting vehicle includes a chassis, a cab, a body, a front axle, a rear axle, an engine, a battery pack, a pump system including a water pump, an electromagnetic device, and a power divider coupling the engine to the pump system and the electromagnetic device. The electromagnetic device is electrically coupled to the battery pack. The electromagnetic device has (a) an output coupled to at least one of the front axle or the rear axle and (b) a power take-off coupled to the pump system.

This application relates to a vehicle control method and system, a vehicle, and a storage medium. The vehicle control method includes: when a braking system fails, activating a backup braking system, the backup braking system decelerating a vehicle by controlling a regenerative motor; when a steering system fails, implementing transverse control over the vehicle by controlling the braking system; and when a parking system fails, implementing parking by controlling a motor and the braking system to work alternately. According to this method, safety control over the vehicle can be implemented when the original braking system, steering system, or parking system fails.

The in-vehicle control device is mounted on a motor vehicle including a shift mechanism having a parking position for performing a shift lock on an axle, an electric parking brake for applying a braking force to a wheel connected to the axle, and an electric motor capable of inputting and outputting power to and from the axle. The vehicle control device performs shock reduction control for suppressing a shock generated in the vehicle by outputting torque corresponding to the inclination angle of the vehicle from the electric motor when releasing the shift lock, and determines whether to perform the shock reduction control when releasing the shift lock according to a state when activating the shift lock and a state after activating the shift lock.

An electrified fire fighting vehicle includes a battery pack, an electric motor, and a controller configured to operate the electric motor using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

An emergency brake system for a heavy-duty vehicle, comprising: a pressure sensor arrangement configured to issue a first signal, S1, upon determination that the pressure in a regular brake circuit is zero or below a predefined pressure threshold value, a speed sensor configured to issue a second signal, S2, upon determination that the speed of the heavy-duty vehicle exceeds a predefined speed threshold, a parking-brake sensor configured to issue a third signal, S3, upon determination that the parking brake is in an applied state, a retarder brake configured to decelerate the heavy-duty vehicle upon activation of the retarder brake, a processing circuitry configured to activate the retarder brake upon receiving all of said three signals S1, S2 and S3.
