A control method includes at least one emission of a radar signal into an area that encompasses a base surface of the roadway section and a wheel of a vehicle, for example an electric bicycle. A radar frequency spectrum reflected on the base surface and on the wheel is subsequently detected using the radar sensor. A control unit actuates at least one brake, for example a front wheel brake of the electric bicycle, as a function of a difference between the vehicle speed and the wheel speed recognized based on the detected radar frequency spectrum.

A transmission control system is configured to be used with a human-powered vehicle that includes a crank, a first rotation body rotated independently from the crank, a drive wheel, a second rotation body rotated independently from the drive wheel, a transfer body that transfers rotation force between the first and second rotation bodies, and a transmission that controls the transfer body and shifts a transmission ratio. The transmission control system includes a motor that drives the transfer body, a first detector that detects at least one of acceleration and vibration of the human-powered vehicle, and an electronic controller configured to control the motor in accordance with a detection result of the first detector upon generation of a shift request for the transmission in a state in which the drive wheel is rotated and a rotational angle of the crank is maintained in a predetermined range.

A suspension control device is provided for a human-powered vehicle. The suspension control device includes a sensor and an electronic controller. The sensor is configured to detect an actuation of a braking system of the human-powered vehicle. The electronic controller is configured to control a suspension of the human-powered vehicle in accordance with the actuation detected by the sensor.

The present disclosure relates to terrain-tracking or vehicle suspension systems that include travel at least one of the front or the rear of the vehicle. Various embodiments include a suspension above the vehicle (upper suspension). Embodiments include a suspension or travel in at least one of the upper vehicle (rear and/or front), middle vehicle (rear and/or front), or below vehicle (rear and/or front). Various embodiments included a combination thereof.

A suspension device of the present invention includes a front wheel-side damper damping force of which is adjustable and which is placed between a vehicle body and a front wheel in a saddled vehicle, a rear wheel-side damper damping force of which is adjustable and which is placed between the vehicle body and a rear wheel, and a control device to control the damping force of the front wheel-side damper and the rear wheel-side damper. Responsiveness in a damping force adjustment of the front wheel-side damper is made higher than responsiveness in a damping force adjustment of the rear wheel-side damper.

A method for operating an electric bike includes a braking system and a drive unit which is actuable in a controlled manner, with the braking system including an actuator which is actuable in a controlled manner for generating a braking torque in a controlled manner. The method includes generating a braking torque in a controlled manner by way of the braking system and generating a driving torque in a controlled manner by way of the drive unit. The generation of the braking torque in a controlled manner and the generation of the driving torque in a controlled manner are performed simultaneously and depending on one another in order to decelerate the electric bike at a predetermined total braking torque, or to accelerate at a predetermined total driving torque.

A control device is provided for a human-powered vehicle including a vehicle body, and a sensor mounted on the human-powered vehicle for detecting at least one of acceleration or inclination. The control device includes an electronic controller configured to set a virtual inclination angle change of the sensor during riding of a rider based on at least one of vehicle body information on of the human-powered vehicle or load information on a load acting on the human-powered vehicle. At least one of the vehicle body information and the load information can be input from an external control device to the control device.

A wheelie suppressing control unit includes: a first determiner that determines whether a vehicle is in a traveling state satisfying a first condition representing a wheelie state; a second determiner that determines whether the vehicle is in a traveling state satisfying a second condition representing a pre-wheelie state which is a state preceding the wheelie state; and a controller that controls the vehicle based on an operation input. If the first determiner determines that the first condition is satisfied, the controller executes first control that reduces the output of a drive source of the vehicle. If the first determiner determines that the first condition is not satisfied and the second determiner determines that the second condition is satisfied, the controller executes second control that restricts a rate of change of the output with respect to the operation input provided to an operation member.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.
