The motor vehicle (1) comprises at least one rear driving wheel (5) and two front steered wheels (7′, 7″). A tilting four bar linkage (11) allows the motor vehicle to perform a tilting movement, for example, when cornering. Support arms (21′, 21″) for front steered wheels (7′, 7″), which rotate around steering axes (21A′, 21A″) and are joined to each other by a steering bar (23), are associated with the tilting four bar linkage. Each wheel is constrained to the respective support arm with the interposition of a suspension (33; 33″). A tilting locking device comprises a brake (53′, 53″) which locks the springing movement of the respective suspension and the tilting movement of the four bar linkage.

A vehicle includes a control switch that is configured to generate an operation signal, and a controller that is electrically connected to the control switch to receive the operation signal therefrom, and that is configured to, in response to receipt of the operation signal, transmit a control signal to a tilting mechanism for making the tilting mechanism operate in one of a locked state and an unlocked state. After the vehicle is powered on, the controller is further configured to, when the controller has continuously received the operation signal for a predetermined reception time, determine that the control switch is abnormal, stop transmitting the control signal and control a warning unit to output a warning signal.

An electronic device includes an artificial intelligence processor that is configured to generate second information for controlling an electric component including at least one of a drive unit that applies propulsion force to a human-powered vehicle, an electric adjustable seatpost, and an electric suspension in accordance with first information related to at least one of the human-powered vehicle, a rider of the human-powered vehicle, and an environment of the human-powered vehicle. The artificial intelligence processor changes a process for generating the second information in accordance with the first information and in accordance with an operation of a first operation unit for operating the at least one of the drive unit, the electric adjustable seatpost, and the electric suspension.

A human-powered vehicle control device includes an artificial intelligence processor, an operation device, and a communication device. The artificial intelligence processor is configured to generate second information for controlling an electric component of a human-powered vehicle in accordance with first information related to at least one of the human-powered vehicle, a rider of the human-powered vehicle, and an environment of the human-powered vehicle. The operation device operates the electric component. The communication device is configured to communicate with an external device. The artificial intelligence processor is configured to change a process for generating the second information in accordance with the first information and an operation of the operation device. The communication device is configured to transmit third information related to a process for generating the second information to the external device.

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 information relating to a ground contact condition. The electronic controller is configured to selectively control a suspension of the human-powered vehicle in accordance with the information detected by the sensor.

A shock absorber assembly including a first sheath slidingly housing inside it a first piston which is filled with hydraulic fluid, the first piston having a first stem extending from the first sheath and a first head contained inside the first sheath, a second sheath slidingly housing inside it a second piston which is filled with hydraulic fluid, the second piston having a second stem extending from the second sheath and a second head contained inside the second sheath. The first and second sheaths are fluidly connected to each other by means of at least one upper duct and a first interconnection duct passing through a control body. The control body houses at least one damping valve including a damping plate having holes suitable to allow a calibrated passage of the hydraulic fluid channelled by the first and second sheaths towards the control body; the control body houses a control valve connected to actuator means to be movable, in a regulation stroke, from an unlocked position, in which it does not interfere with the upper duct to a locked position, wherein the upper duct is occluded.

An electronic device is configured to suitably control of a human-powered vehicle component. The electronic device includes a communicator configured to wirelessly communicate with a pressure detector detecting pressure of at least one tire of the human-powered vehicle. The electronic device is provided in a human-powered vehicle component including at least one of a transmission mounted to the human-powered vehicle, a suspension mounted to the human-powered vehicle, and an adjustable seatpost mounted to the human-powered vehicle.
