A three-wheeled vehicle that includes: a single front wheel; two rear wheels; a passenger cabin; an electronic steering control unit; and a steering input device configured to send an electronic signal to the electronic steering control unit corresponding to an input received at the steering input device associated with turning the three-wheeled vehicle; wherein the electronic steering control unit is configured to counter-steer the front wheel in response to receiving the electronic signal, wherein the counter-steering of the front wheel initiates a leaning of the passenger cabin a direction of turning of the three-wheeled vehicle.

An electric steering device includes a steering retaining device arranged to retain a steering angle against an external steering force applied from outside of a watercraft to an outboard motor main body. A reverse input shutoff clutch, for example, is preferably used as the steering retaining device. A steering retaining state in which a steering angle of the outboard motor main body is retained can be detected from a steering condition of the outboard motor main body, and a control is made to stop electric power from being supplied to an electric motor steering the outboard motor main body. Accordingly, the steering retaining device retains a steering angle while steering is retained, and thus the electric power supply to the electric motor can be stopped, which allows electric power to be saved. The steering retaining device provides an electric steering device for a watercraft in which no electric power is required when applying a steering retaining force for retaining a counter-steering state.

A remote-controlled toy motorcycle includes a chassis supported by oversized front and rear tires for increased stability, and a chassis-mounted rider figure having rotating members for contacting a ground surface to prevent excessive wear of the rider figure legs and also to allow the toy motorcycle to self-start from a leaning position. “Counter-steering” is simulated by actuating a steering servo to initially turn a front wheel from a straight original direction to a direction opposite the desired turn direction. The front wheel is held momentarily while the toy motorcycle destabilizes and leans in the turn direction. Then, the steering servo is automatically actuated to turn the front wheel in the desired turn direction.

A method of controlling implementation of a drift driving state of a vehicle, may include a slip inducement step, wherein in a state that drift mode is selected, when a vehicle enters into rotary driving and is in a power-on state, a controller reduces front wheel distribution torque of all-wheel drive (AWD) system in comparison to cases other than the drift mode; a slip torque control step, wherein when a rear wheel slip of the vehicle is generated, the controller allows the vehicle to enter into drifting by adding slip control torque according to lateral acceleration of the vehicle to the front wheel distribution torque; and a drift maintenance step, wherein when a counter steering state by a driver is confirmed, the controller maintains a drift driving state of the vehicle by releasing all the front wheel distribution torque.

Flexibility in design of steering characteristics is enhanced in a leaning vehicle including two front steerable wheels. A vehicle includes a body frame, a left front wheel, a right front wheel, a rear wheel, a leaning mechanism, a steering mechanism, and a leaning-responsiveness-adjusting mechanism. The leaning mechanism includes arms rotatably supported by the body frame. The arms rotate with respect to the body frame so that the body frame leans. The steering mechanism mechanically transfers rotation of the handle to the left front wheel and the right front wheel. Accordingly, the body frame leans in the direction opposite to the rotation direction of the handle. The leaning-responsiveness-adjusting mechanism controls a motor by using an instruction value based on a time derivative value of a physical quantity generated by a motion of a rider affecting leaning of the body frame to thereby adjust responsiveness of leaning of the body frame.

The invention discloses a backward steering device for propelling and direction control in water. The backward steering device comprises a water spraying propeller, at least two rudders and shift devices, wherein the rudders are respectively arranged on the outer sides of a water spraying opening of the water spraying propeller and used for changing the flow direction of water sprayed by the water spraying propeller; the shift devices are respectively connected with the rudders and used for driving the rudders to deviate from and return to the outer sides of the water spraying opening of the water spraying propeller; one of the water spraying propellers is arranged, and correspondingly a pair of the rudders is arranged and relatively distributed on two sides of a vertical axle wire of the water spraying opening. According to the backward steering device for the propelling and the direction control in water, disclosed by the invention, during the rudders are reduced, a left turn function, a right turn function, a left turn in situ function, a right turn in situ function and a drawing back function can also be realized, so that parts and components are greatly reduced, besides the size is reduced, the weight is lightened, the speed is accelerated, the routine maintenance is convenient, and the related cost is relatively lower.

A steering feel control apparatus of an MDPS may include: a release steering detection unit configured to detect release steering using column torque or motor current; a reverse steering detection unit configured to detect reverse steering using a steering angular velocity or motor angular velocity; a compensation gain detection unit configured to detect a compensation gain using the steering angular velocity or the motor angular velocity; a high frequency input unit configured to filter the column torque or the motor current and input a high frequency; and a compensation gain compensation unit configured to apply the compensation gain detected by the compensation gain detection unit to the high frequency inputted by the high frequency input unit, when release steering is detected by the release steering detection unit or reverse steering is detected by the reverse steering detection unit.

A brake noise at stationary steering is prevented while brake hold being in operation, in automated steering with parking assist control. An automated-parking control unit includes: an environment recognizer to recognize environment of a vehicle; a behavior controller to execute behavior control inclusive of steering and acceleration/deceleration, based on recognized information; a brake hold instructor to suspend the vehicle with the behavior control and hold the vehicle suspended until receiving behavior-related operation by a driver; an automated-parking controller to set a reverse-steering position, based on a current position of the vehicle and a desired parking position decided by the driver, between the current position and the desired parking position, move the vehicle from the current position to the reverse-steering position, and execute stationary steering at the reverse-steering position; and a brake fluid pressure controller to increase a brake fluid pressure when stationary steering is executed at the reverse-steering position.

According to the present embodiments, it is possible to reduce components, e.g., pinion and support yoke, save costs by simplifying the shape and assembly process, reduce operation and reverse steering noise due to inter-gear friction, and driving friction, and enhance durability.
