A dynamic adjustment method while driving a vehicle of at least one vehicle operating parameter is for a vehicle having an electronic control unit adapted to set the operating parameter, and a communication interface operatively connected to the electronic control unit. An application program is installed on board a portable processing device including a communication interface communicating with the vehicle communication interface. The application program accesses an electronic map of a path and divides the path in sectors. Operating parameter values are stored via the application program, each value being associated to a corresponding sector. While driving, the sector occupied by the vehicle is identified in real time. Values are transmitted sector by sector, from the portable processing device to the electronic control unit so that the electronic control unit sets, sector by sector, the vehicle operating parameter vehicle to the value associated to the occupied sector.

A method and the like for controlling a vehicle brake, the method and the like capable of reliably actuating a vehicle departure assistant system even with a particularly inexpensive component configuration.

In one instances, the method for controlling the vehicle brake includes: detecting a stop of a vehicle; determining whether a brake pressure applied to at least one wheel, whose brake pressure has been detected, through an operation by a driver is at least equal to an actuation pressure; activating a departure aid system when it is determined that the brake pressure is at least equal to the actuation pressure; determining whether brake pressure of a rear wheel, which is applied through the operation by the driver, is at least equal to a specified pressure that is required to stop the vehicle; and actuating the departure aid system to automatically retain the brake pressure in a state.

A variable linked braking system controlled by motorcycle speed includes a brake master cylinder; a hydraulic pressure proportion variable valve connected to the brake master cylinder by an oil path; front and rear brake units connected to the hydraulic pressure proportion variable valve by first and second oil paths, respectively; a hydraulic pressure proportion controller for controlling the hydraulic pressure proportion variable valve; a motorcycle speed sensor for converting a sensed motorcycle speed into a speed signal and sending the speed signal to the hydraulic pressure proportion controller; and a brake switch for starting the brake master cylinder and sending a brake signal to the hydraulic pressure proportion controller for controlling the hydraulic pressure distribution proportion of the hydraulic pressure proportion variable valve so that the ratio of braking force of the front brake unit to braking force of the rear brake unit increases with the motorcycle speed.

There is provided a configuration, including a storage unit that stores a theoretical driving wheel rotating speed based on a correspondence relationship with a predetermined engine speed in each gear stage of a transmission of a vehicle; gear stage detection means for detecting the gear stage when currently travelling; engine speed detection means for detecting an engine speed; driving wheel rotating speed detection means for detecting a driving wheel rotating speed; and torque control means for controlling output torque, in which the output torque is increased so that a current driving wheel rotating speed becomes close to the theoretical driving wheel rotating speed when a relative value of a calculated value which is calculated by using the detected driving wheel rotating speed with respect to a calculated value which is calculated by using the theoretical driving wheel rotating speed is equal to or greater than a first threshold value.

One embodiment provides a saddle-ride type vehicle. The vehicle includes a main frame; a drive source supported by a lower side of the main frame; an energy storing part supported by an upper side of the main frame; a front wheel steerably supported via a front fork mounted on a front side of the main frame; a rear wheel supported via a swing arm mounted on a rear side of the main frame and configured to be driven by the drive source; and seat frames disposed on the rear side of the main frame to support a riding seat. A braking control device is disposed within a lateral width between the seat frames, and is supported by a rear fender supported by the seat frame via a vibration control member. And, an inertia measuring device is supported by the braking control device.

A brake system includes a brake activator which reduces, when a slipping condition of a right front wheel is detected based on a signal which is detected by a right detector, both braking forces on the right front wheel and a left front wheel to a lower level than a level of a braking force which is obtained as a result of operation of an input member and which reduces, when a slipping condition of the left front wheel is detected based on a signal which is detected by a left detector, both braking forces on the left front wheel and the right front wheel to a lower level than a level of a braking force which is obtained as a result of operation of the input member.

Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as “weave.” A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.

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.

A braking force control apparatus for a saddle ride vehicle includes a transmission controller which reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel, a clutch device which connects—disconnects the driving force between the engine and the transmission, a brake device which generates braking force on the drive wheel, and a sensor which detects a state of the transmission. The transmission switches between a neutral state and an in-gear state, and when the sensor detects that the transmission is switching from the neutral state to the in-gear state, the controller causes the brake device to generate braking force on the drive wheel, and then releases the braking force upon completion of the switching to the in-gear state.

A variable linked braking system controlled by motorcycle lean angle includes a brake master cylinder; a hydraulic pressure proportion variable valve connected to the brake master cylinder; a front brake unit and a rear brake unit, both connected to the hydraulic pressure proportion variable valve; a hydraulic pressure proportion controller for controlling the hydraulic pressure proportion variable valve; a motorcycle lean angle sensor for sensing a motorcycle lean angle and sending a signal thereof to the hydraulic pressure proportion controller; and a brake switch for starting the brake master cylinder and sending a brake signal to the hydraulic pressure proportion controller for controlling the hydraulic pressure proportion variable valve so that the braking force ratio of the front brake unit to the rear brake unit decreases as the motorcycle lean angle increases, thereby enhancing the stability and traction of a motorcycle being braked in a turn.
