A warning device is provided for use in an electric vehicle which includes a frame member and ground engaging wheels operative mounted relative to the frame member. An electric motor is operatively connected to the frame member and the ground engaging wheels for supplying rotational motion to the ground engaging wheels. A switch member is provided for selectively energizing the electric motor. An indicator member is provided for indicating to an operator that the electric vehicle has completed a preparing to start operation. The switch member may be a switch for operatively connecting the electric motor to a source of power. The indicator member may provide a visual display or an audible sound for warning the operator.

Warning device for an electric vehicle

A controlling device for controlling the transmission ratio of a non-stage transmission in a vehicle. The transmission ratio is controlled according to a forecast output power of the vehicle. The output power is forecast based on an operating condition of the vehicle, such as atmospheric pressure. The control considers various operating parameters. A comparison of a predetermined ratio of increase of engine speed or throttle opening with actual ratios of increase of engine speed or throttle opening may be made in controlling the transmission ratio. An uneven road surface is detected and a transmission ratio of the transmission is controlled accordingly to substantially eliminate hunting. An engine speed is controlled so that the engine speed may not exceed a predetermined rotational speed when the transmission gear ratio is fixed. A target engine speed or target transmission ratio is corrected in response to an output signal of a comparison device which compares an actual vehicle velocity with a set vehicle velocity during automatic fixed vehicle velocity running.

Controlling device for non-stage transmission for vehicles

Apparatus is described for use in a vehicle having a forward motion transmission operatively connected between an engine and the output shaft connecting the drive wheel and a reverse drive mechanism arranged to be operatively connected to the output shaft for driving the vehicle in reverse. A speed change shift device is arranged to operate the forward motion transmission and the reverse drive mechanism so as to prevent simultaneous operation of the two apparatus.

Reverse drive for vehicle

An autobicycle is reversely driven by the driving force of a dedicated reverse driving motor so arranged as to be selectively drivingly connected or disconnected to the rear wheel of the vehicle. The arrangement is particularly adapted for retrofit on existing autobicycles equipped for only powered movement in the forward direction.

Reverse driving device for an autobicycle

A constant speed running control device is disclosed for use on an automobile or motorcycle which permits automatic constant speed operation at a desired speed by a setting operation, and more particularly, to an improvement in a cancellation system for the automatic constant speed operation. The cancellation system being responsive to a throttle opening change in a closing direction of the engine throttle within a fixed period of time which is greater than a predetermined value or is responsive to irregular combustion in the engine during low operating speeds.
