摘要:
The invention relates to a multi-voltage onboard electric system for motor vehicles, comprising at least three flat lines (2a, b, c), which run substantially parallel to one another in their respective longitudinal directions, and at least two voltage sources (4, 6). A first flat line of the flat lines (2a) is connected to a first pole (4a) of a first voltage source of the voltage sources (4) in an electrically conductive manner; a second flat line of the flat lines (2b) is connected to a first pole (6a) of a second voltage source of the voltage sources (6) in an electrically conductive manner; and a third flat line of the flat lines (2c) arranged between the first and the second flat line is connected to a second pole (4b, 6b) of the first and/or second voltage source in an electrically conductive manner.

The purpose of the invention is to provide a hybrid vehicle control system that can start an engine (1) irrespective of a motor rotational speed or runnig scenes. In the hybrid vehicle control device, upon receive of an engine startup request, the engine is started by engaging a first clutch (2) provided between the engine (1) and a motor (3) using the torque of the motor (3) (surplus torque TmOV). A second clutch (4) provided between the motor (3) and the drive wheel (9) is disengaged by a second clutch control means (Step S4) to reduce the motor rotation speed (Nm) as a result of motor (3) rotational speed control by a motor rotation speed-controlling means (Step S6). The control system may thus increase the maximum motor output enable torque to ensure the start of the engine by the surplus torque irrespective of a motor rotational speed or driving scene.

A target-input-torque determination unit determines the target input torque on the basis of the transmission required horsepower. The target input torque is a target value for the torque to be inputted to a power-transmission device. A target-output-torque determination unit determines the target output torque. The target output torque is a target value for the torque to be outputted by the power-transmission device. A command-torque determination unit uses torque-balance information to determine command torque for the motor from the target input torque and the target output torque. The target-input-torque determination unit determines the upper limit of the target input torque on the basis of an upper-limit-target-input-torque line and the engine rotation speed. The upper-limit-target-input-torque line sets a value smaller than the target output torque of the engine determined using the engine required horsepower and the engine rotation speed for the upper-limit value of the target input torque.
