A method for determining an optimized torque distribution to the wheels of a road vehicle comprising the steps of determining a table of distribution of the torque between a front axle and a rear axle; determining a second table and a third table of distribution of the torque between a right wheel and a left wheel of the rear axle and of the front axle, respectively; detecting the current longitudinal dynamics; using the first, the second and the third table to determine a current value of the first, of the second and of the third distribution factor, respectively, based on the current longitudinal speed and on the current longitudinal acceleration of the road vehicle.

When a first type gear shift line is used as a gear shift line to change the gear ratio, and a predetermined condition including a condition that a state of charge of the power storage device is equal to or lower than a first ratio is satisfied, the control device changes the gear shift line to a second type gear shift line that recommends a lower speed gear ratio than the first type gear shift line.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A device for remotely changing the control of power generated by an internal combustion engine of a recreational vehicle driven by a driver controlling an accelerator pedal. The device includes a remote control, sending a signal for modulating the power and/or speed of the engine. The device comprises a system for measuring the position of the accelerator pedal, a system for receiving the signal for modulating the power and/or speed, a system for controlling the intake of gases into the engine, and an electronics module connected to the various systems, establishing rules for controlling the intake control system, depending on the position of the accelerator pedal and the received modulation signal.

A parallel hybrid drive train, in particular for a working machine, includes an internal combustion engine (1), an electrical machine (2) and hydraulic aggregates (3, 4, 5, 9) for driving working devices (6-8) and for moving the working machine. In order to increase the efficiency, the rotational speed of the internal combustion engine is lowered, that is to say the load point is moved. Increased power requirements are detected via a driver input and provide a desired rotational speed. The electrical machine assists the acceleration of the internal combustion engine to said desired rotational speed.

A method of operating a vehicle, such as an autonomous vehicle, includes the steps of receiving a message from roadside infrastructure via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system. Additionally or alternatively, the method may include the steps of receiving a message from another vehicle via an electronic receiver and providing, by a computer system in communication with said electronic receiver, instructions based on the message to automatically implement countermeasure behavior by a vehicle system.

A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.
