[0031] refer to Figure 1 to Figure 7 , and the first embodiment will be described. This embodiment relates to a vehicle control device. figure 1 is a flowchart showing the operation of the first embodiment, figure 2 It is a figure which shows the schematic structure of the vehicle of 1st Embodiment.

[0032] The vehicle control device 1-1 of the present embodiment has a pair of electric motors (refer to figure 2 The reference number 4) is located with the clutch (refer to figure 2 Reference numeral 2) is controlled compared to a vehicle that is closer to the drive wheel side and equipped with a 3-pedal system. The vehicle control device 1-1 is stopping the engine (refer to figure 2 Reference numeral 1) is traveling, the driver selects the engine driving gear and engages the clutch 2 to start the engine 1 . At this time, the electric motor assists to suppress the generation of deceleration feeling until the clutch engagement degree at which the clutch torque can be a...

[0096] refer to Figure 9 to Figure 15 A second embodiment will be described. In the second embodiment, constituent elements having the same functions as those described in the above-mentioned embodiment are denoted by the same reference numerals and redundant descriptions are omitted. Figure 9 is a diagram showing a schematic configuration of a vehicle according to the present embodiment, Figure 10 It is a flowchart showing the operation of this embodiment. In the vehicle control device 1-2 of the present embodiment, the difference from the vehicle control device 1-1 of the above-mentioned first embodiment is that the ECB 50 is provided, and when the brake operation is performed when the clutch for restarting the engine is engaged, the , the target deceleration force depending on the braking operation is divided among the MG torque, the deceleration force due to engagement of the clutch 2, and the deceleration force due to the brakes. Thereby, it is possible to increase ...

Abstract

A vehicle control device includes an engine, a motor disposed nearer to drive wheel sides than the engine in a vehicle, and a clutch disposed between the engine and the motor and configured to be engaged or released according to an operation input, wherein at the time the clutch is engaged to connect the engine and the drive wheels while the vehicle travels with the engine being stopped, the engine is started by the power transmitted to the engine via the clutch as well as the motor is caused to output assist torque for suppressing a reduction of acceleration of the vehicle caused by that the clutch is engaged, and the assist torque when a braking operation is performed is smaller than the assist torque when the braking operation is not performed.

Description

technical field [0001] The present invention relates to vehicle control devices. Background technique [0002] Conventionally, it has been proposed to make the electric motor output torque when the engine is started during travel. For example, Patent Document 1 discloses a technology of a drive control device for a hybrid vehicle that includes assist amount setting means, and when it is judged by the start request judging means that there is a request to start the internal combustion engine In this case, the assist amount setting unit increases the output torque of the motor to the motoring torque (Motoring torque) required to rotate the internal combustion engine or the motoring torque that is obtained by adding the motoring torque and the inertial torque corresponding to the rate of change of the internal combustion engine speed. Torque equivalent torque. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 11-178113 [0004] When the motor is made to o...
