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.

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 (p) is detected based on the determined reference pressure value (p.sub.R), with said decrease exceeding a pressure decrease limit value (p.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.

The invention relates to a method for controlling a waste heat recovery system associated with a combustion engine of a vehicle, the waste heat recovery system comprising a working fluid circuit; at least one evaporator; an expander; a condenser; a reservoir for a working fluid and a pump arranged to pump the working fluid through the circuit, wherein the at least one evaporator is arranged for heat exchange between the working fluid and a heat source, and wherein the waste heat recovery system further comprises a cooling circuit arranged in connection to the condenser. The method comprises the steps of: predicting a shutdown of a combustion engine associated with the system; determining if a predetermined requirement is fulfilled; and if so reducing the temperature in the waste heat recovery system prior to combustion engine shutdown.

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.

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 drive device for a PTO shaft includes a parking switch to detect a parking state of a vehicle body, a permission switch constituted of a self-returning switch and connected to the parking switch, the permission switch being configured to be switched to permit driving a PTO shaft, the PTO shaft being configured to be driven by a power of a prime mover disposed on the vehicle body, and a first switch device to be switched to enable the PTO shaft to be driven when the permission switch is switched to permit driving the PTO shaft under a state where the parking switch detects the parking state of the vehicle body.

An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device 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, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. 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 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.
