A fire fighting vehicle includes a powertrain including an engine, a battery pack, and an electromechanical transmission; a power divider; and a controller. The power divider is positioned between the engine, the pump, and the electromechanical transmission. The controller is configured to monitor a state-of-charge of the battery pack and operate the engine, the power divider, and the electromechanical transmission such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate (i) accelerating the 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. An aggregate of the acceleration time and the period of time is at least three minutes.

A control system for a vehicle may include a brake assembly having a brake actuator that operates brakes to apply braking forces to wheels of the vehicle when actuated, a propulsion system having a propulsion actuator operable to apply propulsive forces to at least some of the wheels when actuated, a hand-operated actuator, and processing circuitry operably coupled to the hand-operated actuator, the propulsion system, and the brake assembly to apply a balancing brake force to balance the propulsive forces generated based on actuation of the propulsion actuator while the vehicle is below a threshold speed and both the hand-operated actuator is actuated and the brake actuator is not actuated, and release the braking forces when the hand-operated actuator is released.

A vehicle includes an engine, an electric generator, a power transmission device, a clutch, and a power generation controller. The electric generator is coupled to the engine. The power transmission device is configured to transmit driving power of the engine to a vehicle's driving wheel. The clutch is provided in the power transmission device and switchable between an engaged state in which the driving power of the engine is transmitted to the driving wheel and a disengaged state in which the driving power of the engine is not transmitted to the driving wheel. The power generation controller is configured to drive the engine and cause the electric generator to generate electric power by using the driving power of the engine. The clutch is switched to the disengaged state when a driver who drives the vehicle is determined to intend to stop the vehicle for a predetermined period or longer.

A vehicle comprises an autonomous driving system and a vehicle platform that controls the vehicle in response to a command received from the autonomous driving system. In the present vehicle, when the autonomous driving system issues a first command to request the vehicle platform to provide deceleration to stop the vehicle and a first signal indicates 0 km/h or a prescribed velocity or less, the autonomous driving system issues a second command to request the vehicle platform to maintain stationary. And after brake hold control is finished, a second signal indicates standstill. Until the second signal indicates standstill, the first command continues to request the vehicle platform to provide deceleration.

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.

A controller for a hybrid electric vehicle includes processing circuitry configured to execute a manual filter regeneration process when satisfying a condition including that execution of the manual filter regeneration process is requested to decrease a PM deposit amount on the filter and that the hybrid electric vehicle is in a stopped state. In the manual filter regeneration process, when a state of charge of the battery becomes less than a discharge threshold value, an output of an internal combustion engine is converted to electric power for charging the battery while the filter is supplied with oxygen from the engine. Further, when the state of charge of the battery becomes greater than or equal to a charge threshold value that is greater than or equal to the discharge threshold value, an output shaft of the engine is rotated with the motor to supply the filter with oxygen from the engine.

A control system for a vehicle may include a brake assembly having a brake actuator that operates brakes to apply braking forces to wheels of the vehicle when actuated, a propulsion system having a propulsion actuator operable to apply propulsive forces to at least some of the wheels when actuated, a hand-operated actuator, and processing circuitry operably coupled to the hand-operated actuator, the propulsion system, and the brake assembly to apply a balancing brake force to balance the propulsive forces generated based on actuation of the propulsion actuator while the vehicle is below a threshold speed and both the hand-operated actuator is actuated and the brake actuator is not actuated, and release the braking forces when the hand-operated actuator is released.

A fire fighting vehicle includes a chassis, tractive elements coupled to the chassis, a pump coupled to the chassis, a discharge fluidly coupled to the pump, an accessory module coupled to the chassis, and an electric motor coupled to the chassis, the pump, and the accessory module. The accessory module is configured to receive a mechanical energy input and provide at least one of electrical energy or fluid energy. The electric motor is configured to provide mechanical energy to drive (a) the pump to provide fluid to the discharge such that the fluid is expelled from the discharge and (b) the accessory module to provide the at least one of electrical energy or fluid energy.

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.

The invention relates to a restarting method for automatically starting an internal combustion engine (2) of a motor vehicle (3) by means of a brake pedal actuation, comprising the following steps: detecting a brake pressure (p) by means of a brake pressure sensor (14); emitting a corresponding brake pressure signal sequence to a control device (13); determining a brake pressure profile (p.sub.pr) from the brake pressure signal sequence; determining a reference pressure value (p.sub.R) from the brake pressure profile; detecting a brake release status, wherein, with the release of a brake pedal, a brake pressure decrease (Δp) is detected based on the determined reference pressure value (p.sub.R), with said decrease exceeding a pressure decrease limit value (Δp.sub.G); emitting a starting signal (S.sub.WS) to a starter (15) for starting the internal combustion engine (2), if the brake release status has been detected. The invention also relates to a restarting assembly for a motor vehicle (1) for carrying out a method of this type.
