The invention relates to a state control system and method for a vehicle with a battery to be swapped. The system includes: a central gateway, a vehicle state control module, and a vehicle state monitoring module that are communicatively connected, where after receiving a state-to-be-adjusted signal, the central gateway sends a control instruction to the vehicle state control module and/or the vehicle state monitoring module; the vehicle state control module and/or the vehicle state monitoring module adjust/adjusts, according to the control instruction, a state of the vehicle with a battery to be swapped; and the vehicle state monitoring module obtains an adjusted vehicle state of the vehicle with a battery to be swapped, and determines whether the vehicle state is a preset vehicle state required for a battery swap process of the vehicle with a battery to be swapped. In the invention, various control modules in the vehicle with a battery to be swapped are communicatively connected, to implement automatic adjustment of a state of the vehicle, so that the state of the vehicle with a battery to be swapped can be quickly and accurately adjusted to a state required for a battery swap process.

A fire fighting vehicle includes a chassis, a front axle, a rear axle, an engine, an energy storage device, an electromechanical transmission, a vehicle subsystem, and a power divider. The electromechanical transmission is (i) coupled to at least one of the front axle or the rear axle and (ii) electrically coupled to the energy storage device. The power divider is positioned between the engine, the vehicle subsystem, and the electromechanical transmission. The power divider includes a first interface coupled to the engine, a second interface coupled to the vehicle subsystem, and a third interface coupled to the electromechanical transmission. The power divider is configured to facilitate (i) selectively coupling the engine to the vehicle subsystem and (ii) selectively coupling the engine to the electromechanical transmission.

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 hybrid vehicle has a first motor/generator mechanically coupled to a drive wheel, a second motor/generator mechanically coupled to an internal combustion engine and a high-power battery that is electrically coupled to the motor/generators. The second motor/generator has a smaller electrical power generation capability than the first motor/generator. While starting the vehicle at a time of insufficient battery capacity required for the EV start, the power generation controller disconnects the first electric motor from the drive wheel, connects the first electric motor to the internal combustion engine, and carries out MG1 idle power generation in which the first electric motor generates power by receiving torque from the internal combustion engine. When the vehicle is stopped at a time of sufficient battery capacity, the power generation controller does not carry out the MG1 idle power generation and keeps the first electric motor mechanically coupled to the drive wheel.

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 control device for a vehicle is provided. The control device includes an electronic control unit that is configured to: exert the torque of an input member on a fixed member and a rotating member such that the fixed member and the rotating member are separated from each other, when the thrust is exerted for making the engagement teeth mesh with each other; estimate an inclination angle of tooth surfaces based on a relative movement amount between the fixed member and the rotating member, and a relative rotational amount between the fixed member and the rotating member; estimate a frictional coefficient of the tooth surfaces based on the inclination angle; and control the thrust of the actuator according to the frictional coefficient.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A computer system, for assisting in coupling and uncoupling a semi-trailer to a tractor vehicle, includes processing circuitry configured to use information provided by at least one sensor to automatically check whether a plurality of elements of the semi-trailer and the tractor vehicle are in a first safe position, in a second safe position or in a third position. The computer system unlocks a tractor vehicle parking brake if all the elements are in the first safe position or if all the elements are in the second safe position and locks the tractor vehicle parking brake if at least one of the elements is in a different position than the others or in the third position.

A vehicle collision avoidance assistance device is configured to perform forced braking or forced steering when a driver's vehicle has a possibility of colliding with an object ahead of the driver's vehicle, acquire at least one of information related to a condition of the driver's vehicle and information related to a situation around the driver's vehicle, determine, based on the acquired information, whether a request condition for requesting execution of the forced steering is satisfied and whether a forbiddance condition for forbidding the execution of the forced steering is satisfied, perform the forced braking when the request condition is not satisfied regardless of whether the forbiddance condition is satisfied, perform the forced steering when the forbiddance condition is not satisfied and the request condition is satisfied, and perform the forced braking when the forbiddance condition is satisfied though the request condition is satisfied.
