A vehicle controller applies a braking force to wheels using a hydraulic braking force generating mechanism and sets a vehicle driving torque, which is generated by an engine, to a second torque which is smaller than a first torque in a normal state, when a switch is switched to an ON state in a state in which a vehicle is traveling and an accelerator is turned on. Then vehicle stops, the vehicle controller implements an EPB mechanical operating state using a mechanical parking brake mechanism. When the switch is switched to an OFF state, the vehicle controller maintains the EPB mechanical operating state until an accelerator pedal operating level reaches 0, and maintains the vehicle driving torque at the second torque. Then the accelerator pedal operating level reaches 0, the EPB mechanical operating state is released and the vehicle driving torque is returned to the first torque.

A control device limits a torque of a drive source until the release of locking by a park lock mechanism is completed if an instruction is given to change from a parking range to a travel range.

Various methods of detecting or controlling vehicle stability are disclosed. Certain embodiments provide a method for performing hill hold control for a vehicle, a method for detecting a vehicle sliding into loss of control, and/or a method for controlling a vehicle's sliding into loss of control. Methods for detecting sliding into loss of control may include comparing the vehicle's longitudinal velocity gradient with a reference speed computed from wheel speed sensors inputs and/or detecting a lateral velocity of the vehicle and a longitudinal velocity of the vehicle when vehicle sliding is detected. Methods for control may include calculating a vehicle pitch angle from the lateral acceleration, the longitudinal acceleration, the yaw rate, the roll rate, and the pitch rate, calculating a longitudinal velocity gradient from the vehicle pitch angle, and/or calculating a sideslip angle.

A method for operating a motor vehicle. The motor vehicle has an electric traction machine. In a first kind of operation of the motor vehicle, before or during a release of a parking brake of the motor vehicle when the motor vehicle is at a standstill, a desired rotational speed for a rotational speed regulation of the traction machine is set to a value corresponding to the standstill of the motor vehicle, and an actual rotational speed of the traction machine is adjusted to the desired rotational speed.

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.

A vehicle control method includes obtaining a first user instruction, where the first user instruction instructs to enable an automatic vehicle hold function; controlling, based on the first user instruction, an automatic vehicle hold system to switch to a wake-up state; obtaining status information of a vehicle; and switching a status of the automatic vehicle hold system based on the status information of the vehicle.

Disclosed is a method for controlling a neutral gear of an automatic transmission. The method includes: when a neutral gear control function of the automatic transmission is in an activated state, an automatic Transmission Control Unit (TCU) collects information on a pressure of a brake main cylinder, a state of a brake pedal, and whether an autohold function is in an activated state or not; and when the pressure of the brake main cylinder is smaller than a pressure threshold P.sub.3 of the neutral gear control function and the autohold function is in an inactivated state, or when the brake pedal is in an unstamped state and the autohold function is in the inactivated state, the automatic TCU controls the neutral gear control function to exit from the activated state.

A method of operating a drive-train (1) of a motor vehicle, in particular an agricultural or municipal utility vehicle, having a drive engine (2), a motor vehicle transmission (4) and at least one drive axle (6). A connection between the drive engine (2) and the at least one drive axle (6) of the motor vehicle is separate automatically by way of a function, and a service brake (11) of the motor vehicle has to be actuated for activation of the function. To ensure an appropriate starting gear selection in various operating situations, during the course of the function triggered by a braking process, a brake pressure (p.sub.Brems), applied during the process, is determined and a starting gear is automatically determined as a function of the brake pressure (p.sub.Brems).

A method for operating a vehicle that includes: generating, by at least one processor, a start trigger signal based on first driving situation information; in response to the start trigger signal, performing, by the at least one processor, a storage operation that stores in at least one memory (i) driving manipulation data that is generated based on user input from a user of the vehicle, and (ii) navigation data that is generated corresponding to the driving manipulation data; generating, by the at least one processor, an end trigger signal based on second driving situation information; and in response to the end trigger signal, stopping, by the at least one processor, the storage operation that stores the driving manipulation data and the navigation data is disclosed.
