Various systems and methods associated with protecting a rider of an electric bicycle from hazards while riding their bicycle are described. In some embodiments, the systems and methods enhance the safety of the rider in response current detected conditions surrounding the rider, such as conditions associated with the route or path traveled by the rider, other vehicles within the route or path traveled by the rider, potential hazards within the route or path traveled by the rider, environmental conditions through which the rider is traveling, and so on.

A method for controlling an electric vehicle and the electric vehicle are provided. The method includes: under a condition in which the electric vehicle is in unlocked and motor control shielded states, first predetermined information is detected, wherein the first predetermined information is used for indicating that a rider is located on the electric vehicle; the electric vehicle is controlled to switch from the motor control shielded state to a motor control unshielded state; a predetermined control signal is received in the motor control unshielded state; and a motor of the electric vehicle is controlled to rotate according to a rotational speed corresponding to the predetermined control signal. With the disclosure, the problems of complex operation and poor user experience of a manner for controlling the electric vehicle in the related art are solved.

A snowmobile including a warming element at a handlebar of the snowmobile. The warming element is configured to generate heat in response to electrical current driven therethrough. A user interface is configured to receive inputs from an operator of the snowmobile. The inputs include a first temperature input setting a first predetermined temperature for the warming element. A control assembly includes a warmer control button configured for setting the warming element at the first predetermined temperature. A control module is included with the control assembly and in receipt of inputs from the user interface and the control assembly. The control module is configured to, when the first predetermined temperature is selected by way of the warmer control button, direct sufficient electrical current to the warming element to generate heat equal to the first predetermined temperature.

A bicycle safety enhancement device includes an elongated member having a distal portion mountable to a bicycle handlebar. A proximity sensor is coupled to a proximal portion of the elongated member and is arranged so that when the elongated member is mounted to a handlebar of a bicycle being ridden by a cyclist, the ultrasonic sensor detects objects adjacent to and/or behind the bicycle and which come within a prescribed distance of the bicycle. An illumination source is coupled to the proximal portion of the elongated member. The illumination source provides a visible warning signal directed toward the detected object when the elongated member is mounted to the handlebar of the bicycle. A camera is coupled to the proximal portion of the elongated member and is arranged to capture images of the detected object as the detected object passes in front of the bicycle being ridden by the cyclist.

Bicycles and automobiles share the roads and it is imperative that a collision between a car and a bicycle be avoided. A warning system that can be placed on the back of a bicycle that extends upward to alert the general traffic in the area. The top portion of the pole will be equipped with a flag or other warning device and will also be illuminated for greater visibility. The warning system can also be extended outward to alert oncoming traffic to a bicycle in the area. When the arm is extended outward it can also rotate backwards if the warning device is struck by an obstacle.

This vehicle transmission system includes a transmission (21) in which a gear is shifted by an operation of a driver of a vehicle (1), a clutch device (26) that is disposed in a motion transfer path between the transmission (21) and an engine (13) of the vehicle (1), and is disconnected and connected by an action of a clutch actuator (50), and a clutch control unit (61) that is configured to control disconnection and connection of the clutch device (26) by the clutch actuator (50). In a case where the vehicle (1) is started with a gear position of the transmission (21) located at or above a gear that is set in advance, and a vehicle speed (V) is less than or no higher than a set value (v2) that is set in advance, the clutch control unit (61) transitions to clutch capacity-limiting control in which a clutch capacity is reduced below that during normal clutch control.
