Embodiment Construction
[0062] Next, embodiments of the present invention will be described below with reference to the drawings.
[0063] figure 1 An example of a brake hydraulic circuit constituting a brake control device for a motorcycle as a vehicle according to the present invention is shown. This hydraulic circuit is mainly composed of a front wheel hydraulic circuit 100 , a rear wheel hydraulic circuit 200 , and a DC motor 300 that drives the respective hydraulic pumps 119 , 219 of the front wheel hydraulic circuit 100 and the rear wheel hydraulic circuit 200 .
[0064] First, the configuration of the front wheel hydraulic circuit 100 will be described. The front wheel hydraulic circuit 100 includes a brake lever 101 operated by the driver's right hand, a front wheel side master cylinder 103 that is pressurized when the brake lever 101 is operated, and a front wheel side master cylinder 103 connected to the front wheel side master cylinder 103. The accumulator 105 for the wheel side master p...

The present invention provides a method, etc., for controlling a vehicle brake, with which it is possible to reliably operate a vehicle departure assistance system even when using a particularly inexpensive component configuration. This method for controlling a vehicle brake has: a step S10 for detecting the stopping of a vehicle; a step S12 for determining, with respect to at least one vehicle wheel for which brake pressure has been detected, whether or not the brake pressure applied due to an operation performed by a driver is equal to or greater than an operating pressure; a step S14 for starting a departure aid system when the brake pressure is determined to be equal to or greater than the operating pressure; a step S18 for determining whether or not the brake pressure on a rear wheel applied due to an operation performed by the driver is equal to or greater than a prescribed pressure required for stopping the vehicle; and steps S20, S22 for operating the departure aid system and automatically holding the brake pressure unchanged when the brake pressure on the rear wheel is greater than or equal to the prescribed pressure, and operating the departure aid system, increasing the brake pressure to at least the prescribed pressure, and then automatically holding the brake pressure when the brake pressure on the rear wheel is less than the prescribed pressure.
Description
technical field [0001] The present invention relates to a vehicle brake control method and device for assisting the start of the vehicle, and more specifically, to a vehicle brake control method and device that are inexpensive even without installing expensive parts such as a gradient detection sensor. In addition, not only slope roads, but also horizontal roads (flat roads) can reliably operate the start support system to support the start of vehicles, especially motorcycles. Background technique [0002] In a vehicle such as a motorcycle, a conventional brake control device having a hill start support system added with a function for supporting a hill start uses a gradient detection sensor to support a hill start when parking on an uphill road. The system operates to automatically maintain the brake pressure, and as a mechanism for canceling the operation of the hill start support system, the following structure is adopted: In addition to the slope information of the road ...
