Problems solved by technology

[0006] However, when the engine braking torque control is performed during the antilock braking control, if the engine braking torque control is performed based on the slip amount in the same manner as when the antilock braking control is not performed, the locking tendency of the wheels will When recovering, the engine brake is applied excessively, and the wheels tend to lock up

Embodiment Construction

[0042] Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[0043] Such as figure 1 As shown, the vehicle CR has an ECU (Electronic Control Unit) 200 , a vehicle brake fluid pressure control device A as an example of a vehicle control device, and an engine EG (internal combustion engine) as an example of a drive source.

[0044]ECU 200 is a control device that controls the entire vehicle including control of engine EG, is connected to control unit 100 of vehicle brake fluid pressure control device A through a communication line, and can exchange signals with control unit 100 . In addition, a torque sensor 92 for detecting the engine torque of the engine EG and an engine rotational speed sensor 93 for detecting the rotational speed of the engine EG are connected to the ECU 200 .

[0045] The ECU 200 has, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Onyy Memory), and an...

Abstract

An object of the present invention is to provide a vehicle control device that satisfactorily controls the braking torque of a driving source in antilock braking control. The vehicle control device (vehicle brake fluid pressure control device A) has a torque increase amount setting for setting the torque increase amount of the driving torque of the wheels used in the driving source braking torque control for controlling the driving source braking torque. Means (150); anti-lock brake control means (160) capable of performing anti-lock brake control controlling brake pressure applied to wheels. The torque increase amount setting means (150) has a first setting for setting the torque increase amount based on at least the slip amount of the wheel when the driving source braking torque control is being executed and the antilock brake control is not being executed. A means (151), a second setting means (152) for setting a torque increase amount based on a parameter different from the slip amount when both the driving source braking torque control and the anti-lock braking control are being executed.

Description

technical field [0001] The present invention relates to a torque increase amount setting device having a torque increase amount used in a driving source braking torque control for controlling a driving source braking torque applied to a wheel from a driving source of a vehicle, and an antilock brake. A control device for a vehicle of a control device. Background technique [0002] Conventionally, an engine braking torque control is known as a vehicle control device for suppressing wheel locking by controlling engine torque when the wheels tend to lock due to engine braking (see Patent Document 1). Specifically, in this technique, engine torque is controlled based on the amount of wheel slip. [0003] Conventionally, anti-lock brake control is known as a vehicle control device that controls brake hydraulic pressure to suppress wheel lock when the brake hydraulic pressure tends to lock the wheels (see Patent Document 2). Specifically, in this technique, the brake hydraulic p...
