It is an object of the present invention to control unstable behavior of a vehicle body that arises when braking during turning. A brake control method for when a two-wheeled motor vehicle is turning includes the steps of: judging whether or not the two-wheeled motor vehicle is turning; calculating a maximum braking force with which slipping of a front wheel will not arise and updating, on the basis of the calculation result, a stored maximum braking force for the front wheel; calculating a maximum braking force with which slipping of a rear wheel will not arise and updating, on the basis of the calculation result, a stored maximum braking force for the rear wheel; limiting the braking forces on the front wheel and the rear wheel to predetermined percentages of the corresponding maximum braking forces in a case where there has been a brake operation by a driver during turning; and bringing the braking forces on the front wheel and the rear wheel that have been limited closer to the corresponding updated maximum braking forces.

Brake system and brake control method

A vehicle braking force control device which, at a normal time, performs antilock brake control when the slip ratio of a wheel has become equal to or greater than a predetermined threshold. The control device acquires from the engine control unit an accelerator pedal position signal corresponding to an accelerator pedal position, a clutch connection signal corresponding to a state of connection of a clutch, and a power transmission signal corresponding to a state of power transmission of a transmission. When engine braking is large on the basis of the accelerator pedal position signal, the clutch connection signal, and the power transmission signal, the vehicle braking force control device changes the predetermined threshold value to an offset threshold value that makes it harder to perform the antilock brake control than at the normal time.

Technology for realizing reductions in time required for production plan by estimating supply capacities of suppliers is provided. A system has a function of registering and displaying transaction information including delivery requests from a buyer including number of required parts and delivery responses from a supplier including number of suppliable parts, a function of managing the series of transaction information as transaction history information on a DB, and an estimating function of estimating supply capacities of parts of the supplier with respect to the delivery responses in reply to delivery requests. The estimating function performs processes of estimating supply capacities by determining numbers of suppliable parts of past delivery responses with respect to numbers of required parts of past delivery requests by using the delivery request history information, the delivery response history information and the process LT information, and outputting a screen including the estimated result information to users.

To further improve, in a brake control method and device for a two-wheeled motor vehicle that utilizes a wheel cylinder pressure as a parameter for predicting the potential for lifting of a rear wheel, the accuracy of predicting lifting of the rear wheel. A brake control method of the present invention comprises the steps of inputting a signal of an input sensor (step); detecting a front wheel cylinder pressure (step); detecting an amount of change in the front wheel cylinder pressure (step); determining whether or not the front wheel cylinder pressure and the amount of change in the front wheel cylinder pressure that have been detected correspond to a brake condition where lifting of a rear wheel can occur (step); and, when it is determined that the front wheel cylinder pressure and the amount of change in the front wheel cylinder pressure that have been detected correspond to the brake condition, reducing a pressure amplification gradient of the front wheel cylinder pressure.

To enable, with respect to a vehicle whose vehicle body is easily lifted to a relatively large extent even in a relatively early stage when rear wheel lifting is detected, more rapid and reliable securement of the safety of the vehicle body with respect to that rear wheel lifting. When lifting of a rear wheel is detected, in contrast to what has conventionally been the case, pressure reduction of brake pressure of a front wheel is immediately started (S, S) regardless of whether or not there is occurrence of skidding of the front wheel, a stepwise reduction of brake pressure is performed while lifting of the rear wheel is being detected, and when the integrated amount of that amount of pressure reduction reaches a predetermined value, pressure reduction is ended even in a state where rear wheel lifting is being detected.

Two-wheeled motor vehicle brake control method and system

To reliably prevent re-lifting of a rear wheel immediately after landing of the rear wheel. When it is determined that output of a detection signal corresponding to detection of lifting of a rear wheel has ended (S), brake pressure&#x2014;and specifically a pressure increase gradient of a wheel cylinder pressure of a front wheel&#x2014;is reduced, and the pressure increase gradient that has been reduced is maintained until it is determined that vehicle body deceleration has fallen below a predetermined value K(S, S), whereby re-lifting of the rear wheel caused by an increase in brake pressure at a high pressure increase gradient after landing of the rear wheel can be reliably prevented.

Two-wheeled motor vehicle brake control method and brake control system

A two-wheeled motor vehicle brake control method and system which immediately reduces the brake pressure of the front wheel when rear wheel lifting is detected regardless of whether or not the front wheel is skidding. The reduction in brake pressure can be an amount which corresponds to the amount of lifting. The reduction in brake pressure can be performed in a stepwise manner until lifting is no longer being detected; it can be performed in a stepwise manner with a limit on the number of steps; or it can be performed in a stepwise manner until a total pressure reduction amount is achieved.

To predictively determine the occurrence of rear wheel lifting before actual lifting of a rear wheel occurs and enable control of brake force. Vehicle body deceleration is computed on the basis of wheel velocities obtained by wheel velocity sensorsand(S), and when it is determined that that computed value exceeds a predetermined value K(S), then the pressure of a front wheel cylinderis reduced by a predetermined pressure and held at that reduced pressure (S), and when it is determined that vehicle body deceleration has fallen below a value that is, for example, lower by a predetermined value &#x3b1; than the predetermined value K(S), then the state of holding of the pressure of the front wheel cylinderis released (S) and brake control returns to normal brake control.
