The intelligent line control braking system for the two-wheel vehicle can realize active control braking, solve the problem that wheels of the two-wheel vehicle are locked in the braking process, and increase the driving safety coefficient. The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, the intelligent brake-by-wire system for the two-wheeled vehicle comprises a manual brake mechanism assembly, a brake-by-wire master cylinder assembly and a brake caliper brake disc assembly, wherein the brake-by-wire master cylinder assembly comprises: the cylinder comprises a first pressure sensor 2, a piston 6, a cylinder body 4, an oilcan 5, a second pressure sensor 7, a cylinder body rear cover 8, a controller 9, a transmission mechanism 13, a motor rotor 14, a motor stator 15, a cylinder body front cover 16 and a spherical hinge 17. The manual brake assembly includes: the brake handle 1 is fixed on the handlebar 18, and the main function of the brake handle is that the manual brake assembly is connected with the piston 6 on the wire control master cylinder assembly through the brake handle 1 to transmit the manual brake force to the piston 6; the brake caliper brake disc assembly includes: calipers 10, wheel speed sensors 11, and brake discs 12.
According to actual working conditions, the intelligent line control motor system for the two-wheel vehicle works in four conditions:
1) Normal deceleration
Under this operating mode, the driver is changing and pinching brake handle 1, and first pressure sensor 2 detects that the intention of driver is urgent brake to feed back to the controller, at this moment the controller does not output the order and lets the motor work, and braking force directly transmits the piston rod through brake handle 1, and the piston rod is to cylinder bottom direction motion and is supercharged and pass through the pipeline with oil pressure transmission for brake caliper brake disc assembly and slow down. The hydraulic pressure is mainly generated by the driver pinching the brake handle 1 to push the piston 6 to push the caliper 10 to brake, and the motor does not work at this time.
2) Emergency braking
Under the working condition, when a driver encounters an emergency, and the brake handle 1 is pinched with full force, the first pressure sensor 2 detects that the intention of the driver is emergency braking and feeds back to the controller, the controller 9 can output a command to enable the motor to be rapidly involved in to enable the motor to work, and the wheel speed sensor 11 feeds back signals to the controller to perform forward and reverse rotation to perform oil pressure adjustment, the wheel speed sensor 11 detects that the wheel hub is rapidly locked, the motor drives the piston to move in the direction of increasing the volume of the main cylinder cavity, otherwise, the motor drives the piston to move in the direction of reducing the volume of the main cylinder, and the motor reciprocates until the vehicle is stopped stably.
3) Active braking
If the vehicle is provided with a ranging sensor, the technical scheme can be matched with the ranging sensor to perform active braking, and the specific working principle is that the ranging sensor is too close to the front vehicle, signals are fed back to the controller, and the controller can control the motor to perform active braking.
4) Braking standby
After braking is completed, the second pressure sensor 7 can feed back a position signal of the piston 6 to the controller 9, and the controller 9 controls the motor to drive the piston to return to the original position through the transmission mechanism 13 so as to carry out pressure regulation for subsequent braking.
