A control apparatus for controlling a vehicle includes a driving motor configured to drive the vehicle by outputting motor torque based on a supply voltage from a battery, and an engine configured to drive the vehicle by outputting engine torque. The control apparatus may acquire driving mode data which is calculated based on traffic information from the current position to the destination of the vehicle and dimension information of the vehicle, and control the vehicle to drive to the destination according to a driving mode which is determined by applying a travelling condition of the vehicle to the acquired driving mode data, where the power distribution ratio of the motor torque to the engine torque is reflected in the driving mode data.

A control device of a vehicle, the vehicle having: a power source including an engine and an electric motor; and a power transmission shaft to which the power source is coupled in a power transmittable manner; the vehicle comprising: a power transmission device transmitting a torque of the power source input to the power transmission shaft, to driving wheels; and an electric-power accumulator supplying/receiving electric power to/from the electric motor, the control device comprising: a power source control unit performing charge control for increasing a torque of the engine that achieves a drive demand amount during running of the vehicle in a driving state; and a charge limit control unit performing charge limit control for limiting a charging power in the charge control.

A method of operating a motor vehicle. A request for coupling a power take-off is detected. It is checked (12) whether relevant boundary conditions for coupling the power take-off are fulfilled. If the boundary conditions are fulfilled, a system pressure for actuating the power take-off clutch is built up (16). It is checked (18) whether sufficient system pressure to actuate the power take-off clutch has been built up. When sufficient system pressure has sufficiently been built up, a confirmation signal is produced (20). In reaction to the confirmation signal, a driving transmission control unit is modified (34) in order to actuate the at least one shifting element of the driving transmission with a higher actuation pressure than with an unmodified driving transmission control unit.

In a driven state phase, target input torque is limited to a first limit value, whereas in a backlash-elimination state phase, the target input torque is limited to a second limit value and target engine torque and torque of a motor-generator are controlled according to the target input torque. In the backlash-elimination state phase, the target input torque is limited to the second limit value that is suitable for mitigating rattling shock, so that rattling shock can be appropriately mitigated. Meanwhile, in the driven state phase, the target input torque is limited to the relatively high first limit value, so that an MG rotation speed can be quickly increased to eliminate a rotational difference, which enhances the responsiveness of driving power up to when required driving power is obtained after elimination of the backlash.

A method for allocating power between electric machines in a powertrain of an electric vehicle is described. The electric vehicle includes a gearbox having an input shaft and an output shaft configured to transmit a first torque to the wheels of the vehicle, a first electric machine having an output shaft coupled to the input shaft of the gearbox, and a second electric machine configured to supply a second torque to wheels of the vehicle. The method comprises: prior to a gear change of the first electric machine, allocating power to the first and second electric machines according to a first power ratio; in response of an intended gear change of the first electric machine, allocating power to the first and second electric machines according to a second power ratio.

A vehicle driving apparatus includes: an engine; a fluid transmission device; first and second rotary electric machines; an output shaft for receiving a power transmitted through a first power transmission path and outputting the power to one of a pair of front wheels and a pair of rear wheels; and a control device for controlling an engine operation point by adjusting an electrical path amount between the first and second rotary electric machines. The second rotary electric machine outputs the power to the other of the pair of front wheels and the pair of rear wheels, through a second power transmission path. The control device obtains a target electrical path amount enabling the engine operation point to become a target operation point, and causes a speed change device provided in the second power transmission path to establish a gear ratio enabling the target electrical path amount to be attainable.

The present disclosure provides a multi-stage method to extend the range of a vehicle. The method includes taking progressive actions on a vehicle as the state of charge (SOC) drops below defined levels. The method may include monitoring the SOC of the vehicle in relation to a SOC threshold or monitoring the SOC of the vehicle in relation to the distance remaining to a predetermined destination.

The disclosed computer-implemented method may include tracking personal mobility vehicle batteries. In some embodiments, the method may track and maintain battery power for personal mobility vehicles to help to ensure that there are personal mobility vehicles with sufficient charge available to perform the needed transportation tasks within a dynamic transportation network. In some examples, a swappable battery for a personal mobility vehicle may communicate with a dynamic transportation management system and provide information about current and/or historical charge information. In some examples, the method may use the current state of charge and/or historical charge information to predict the performance of the battery. Based on the predicted performance, the method may predict the range of a personal mobility vehicles with the battery and/or a lifespan of the battery and make matching decisions accordingly. Various other methods, systems, and computer-readable media are also disclosed.

A hybrid electric vehicle includes an engine, a motor, a battery, a coupling mechanism, an electric power generating mechanism, and a vehicle controller. The engine and motor drive driving wheels. The battery supplies electric power for running to the motor. The coupling mechanism switches coupling of the engine and the driving wheels between direct coupling and buffering coupling. The electric power generating mechanism generates electric power. The vehicle controller switches a running mode of the hybrid electric vehicle between a first running mode and a second running mode with higher running performance. The vehicle controller limits the electric power generation under a first condition when the buffering coupling is applied during the first running mode and limits the electric power generation under a second condition less limited than the first condition when the buffering coupling is applied during the second running mode.

A vehicle includes an engine including a forced induction device, a knock sensor and a crank angle sensor that detect an occurrence of LSPI, a battery that supplies electric power to a second motor generator, and an ECU. When an occurrence of the LSPI is detected, the ECU restricts a maximum torque, which can be output by the engine with the forced induction device, more than when an occurrence of the LSPI is not detected to prevent an engine operating point from being included in an LSPI area, and when an output of the engine becomes insufficient along with the restriction on the maximum torque, the engine compensates for an amount of the insufficient output with electric power supplied from the battery.
