A system for multiple brakes intelligently controlled by a single brake input on a personal mobility vehicle. By determining a front and rear brake differential based on the position and weight of the rider as well as the environmental and vehicle conditions, the system may reduce the risk of the vehicle skidding or tipping due to over-braking. In some embodiments, a rider may use a single brake lever to indicate a desire to brake and the system may make determinations about how to apply a combination of mechanical and electrical brakes to front and back wheels. By applying different braking systems based on a combination of controls and sensors, the system may improve user experience and user safety, especially for inexperienced riders.

The present invention is to provide a brake hydraulic pressure control device and a brake hydraulic pressure control method capable of preventing a rear wheel from lifting. Also, the present invention is to provide a saddle-type vehicle including the brake hydraulic pressure control device.

According to the present invention, there is provided a brake hydraulic pressure control device of a saddle-type vehicle, which is configured to execute anti-lock brake control and determines the time for one opening of a hydraulic pressure adjusting valve when the pressure of a brake fluid in a wheel cylinder is increased while the hydraulic pressure adjusting valve is repeatedly opened and closed, in correspondence to the pressure of the brake fluid in a master cylinder and an input gradient, which is an increment per unit time of the amount of operation of an input unit of a brake.

A hydraulic control valve for an ATV or motorcycle takes hydraulic input from a hand brake lever as an input to a first cavity of the control valve with a movable piston therein, and from a foot brake lever as an input to a second cavity of the control valve with a movable piston therein, with the two pistons being linked. A bypass channel extends around the piston in the first cavity, which is closed off when the first piston moves longitudinally. The output of the first cavity hydraulically controls braking of the front wheel(s). The foot brake lever also pressurizes a direct line to brake the rear wheel(s) that doesn't go through the control valve.

The disclosure relates to a scintillator material for a radiation detector. In an embodiment, the scintillator material can include a crystalline alkaline-earth metal halide comprising at least one alkaline-earth metal selected from Mg, Ca, Sr, Ba, said alkaline-earth metal halide being doped with at least one dopant that activates the scintillation thereof other than Sm.sup.2+, and co-doped with Sm.sup.2+, said alkaline-earth metal halide comprising at least one halogen selected from Br, Cl, I.

This invention relates to a hydraulic brake device with a time difference, which utilizes an innovative brake structure to realize the time difference braking technique in which the rear wheel preferentially activates the braking action, to prevent the vehicles from slipping or spillover. Moreover, said time difference hydraulic brake device in the present invention can increase the braking force of the front wheel brake, this allows bicycles, motorcycles, electric scooters, automobiles and other vehicles to effectively improve braking performance and safety.

A brake fluid pressure control device for vehicles with bar handle, includes: an acceleration acquiring unit which is configured to acquire acceleration that occurs in the vehicle; and a control unit which is configured to judge a probability of occurrence of a rear-wheel lift based on the acceleration acquired by the acceleration acquiring unit, and which is configured to perform a pressure reduction control on a front wheel brake when judging that the occurrence of the rear-wheel lift is probable, the control unit which is configured to adjust a degree of pressure reduction of the pressure reduction control based on a differentiation value of the acceleration acquired by the acceleration acquiring unit.

A hydraulic control valve for an ATV or motorcycle takes hydraulic input from a hand brake lever as an input to a first cavity of the control valve with a movable piston therein, and from a foot brake lever as an input to a second cavity of the control valve with a movable piston therein, with the two pistons being linked. A bypass channel extends around the piston in the first cavity, which is closed off when the first piston moves longitudinally. The output of the first cavity hydraulically controls braking of the front wheel(s). The foot brake lever also pressurizes a direct line to brake the rear wheel(s) that doesn't go through the control valve.

The invention obtains a controller and a control method capable of appropriately assisting with an operation by a driver while preventing a motorcycle from falling over.

In the controller and the control method according to the invention, in a control mode to make the motorcycle perform an automatic cruise deceleration operation, automatic deceleration that is deceleration of the motorcycle generated by the automatic cruise deceleration operation is controlled in accordance with a lean angle of the motorcycle.

A vehicle brake control device including a front wheel speed acquisition section, a rear wheel speed acquisition section, a front wheel acceleration calculation section, a rear wheel acceleration calculation section, a front wheel anti-lock brake control section capable of executing an anti-lock brake control for the front wheel, a vehicle acceleration acquisition section, and a bad road determination section configured to determine whether or not a running road surface is a bad road based on the front wheel acceleration or the rear wheel acceleration. The bad road determination section executes a bad road determination by selectively using one of the front wheel acceleration and the rear wheel acceleration at least based on information on whether or not the anti-lock brake control for the front wheel is executed and the vehicle acceleration.

To provide a brake piping structure for saddled vehicle which can reduce the number of restraining members used for brake piping and allow brake piping to avoid interfering with other parts. The brake piping structure for saddled vehicles includes a pair of left and right rear frames connected to a rear portion of a vehicle body frame of a saddled vehicle and supporting a seat, a swing arm swingably supported, via a pivot, by the vehicle body frame, and brake piping which conveys hydraulic pressure generated by an ABS modulator to a rear brake caliper for a rear wheel. The ABS modulator is disposed between the pair of left and right rear frames. The brake piping extends from the ABS modulator forward and downward of the vehicle body along the rear frame and is, by being curved rearward of the vehicle body in front of the pivot and then by being routed under the swing arm, connected to the rear brake caliper.
