A brake system has at least two electromechanical wheel brakes and a central control unit. Each wheel brake has a wheel-specific control unit for controlling the deceleration moment exerted on a vehicle wheel by the respective wheel brake. The brake system has at least one rotational speed sensor per vehicle wheel. The central control unit is connected to the wheel-specific control units of the wheel brakes via a data bus for the exchange of control signals. The rotational speed sensors are each directly connected to the wheel-specific control unit of the wheel brake of the respective vehicle wheel for transmission of the ascertained rotational speed information. The wheel-specific control units are each configured to control a deceleration moment exerted by the respective wheel brake on the respective vehicle wheel on the basis of the received rotational speed information and the control signals received from the central control unit.

The present invention obtains a controller and a control method capable of appropriately emitting an emergency braking signal in a straddle-type vehicle.

A controller (60) and the control method according to the present invention control operation of a straddle-type vehicle (100) in which anti-lock brake control for a front wheel (3) and anti-lock brake control for a rear wheel (4) are executed. An acquisition section of the controller (60) acquires an anti-lock brake actuation state showing whether the anti-lock brake control is actuated for any of the wheels (3, 4). A determination section of the controller (60) determines a threshold value on the basis of the anti-lock brake actuation state. An output section of the controller (60) outputs an emergency braking signal command in the case where deceleration of the straddle-type vehicle (100) is higher than the threshold value.

A hydraulic unit for a slip-controlled brake system, the simulator receiving hole of which is aligned transversely to a master cylinder hole in a receiving body of the hydraulic unit, thus enabling a section of the simulator to be received in a cap of a control unit.

A braking control device executes pre-stop braking control to adjust a braking force when a vehicle stops. The pre-stop braking control includes reduction control that reduces the braking force, and increase control that is executed before the reduction control is started, to increase the braking force. An increasing unit executes the increase control, and a reducing unit executes the reduction control. A calculation unit calculates a braking distance extended by the reduction control, as an extended distance, and calculates a braking distance shortened by the increase control, as a shortened distance. The calculation unit calculates the extended distance to become longer when an operation amount of a braking operation member operated by a driver is reduced during braking than when the operation amount is not reduced. When a difference between the extended distance and the shortened distance is less than a determination value, the reducing unit starts the reduction control.
