The invention provides a multifunctional impulse type well borer, which comprises a bay, a main generator, a main drive shaft, and a clutch assembly, a front-wheel-drive generator, a rear-wheel-drive generator, and a front-wheel-steering generator, a front-wheel-drive shaft with a front bridge tooth packet and a rear-wheel-drive shaft with a rear axle tooth packet are respectively mounted on the front portion and the rear portion of the bay, a front wheel and a rear wheel are respectively mounted on the front-wheel-drive shaft and the rear-wheel-drive shaft, an output shaft of a front wheel speed changing box which is connected with an output shaft of the front-wheel-drive generator is connected with a front-wheel-drive transmission shaft in the front bridge tooth packet, a front wheel steering balancing holdfast tube body whose bottom end is connected on a casing body of the front bridge tooth packet is sleeved on the outer of the speed changing box and the front-wheel-drive transmission shaft, and the front wheel steering balancing holdfast tube body is driven by the front-wheel-steering generator through a front-wheel-steering transmission mechanism, a rear axle drive shaft is driven by the rear-wheel drive generator through a rear axle gear wheel drive mechanism, and an input shaft of a rear axle tooth packet is connected with a rear axle drive shaft. The invention has the advantages of time saving and labor saving, strong climbing property, stability, flexible steering, and big turning radius.

The invention discloses a method for travelling of motor vehicles at an intersection in a mode of going straight or turning right firstly and then turning left. The motor vehicles travel on a motor vehicle lane in the first direction can go straight without a limit to pass the intersection 0; the motor vehicles travel on a motor vehicle lane in the second direction cannot straightly go through the intersection 0 but can turn right to pass the intersection 0 and then turns left so that any motor vehicle J can directly go straight, or indirectly turn left, or indirectly turn round or indirectly go straight to pass the intersection 0 without a limit, and accordingly the motor vehicles J can easily go through the intersection 0 smoothly. The invention further discloses a specific lane for helping the motor vehicles J to go through the intersection 0 smoothly. The specific lane E comprises the intersection 0, the motor vehicle lane F in the first direction, a forward lane of the motor vehicle lane F, and G'; the G' comprises the motor vehicle lane G in the second direction; and the specific lane E comprises signs for determining the motor vehicle lane F and the motor vehicle lane G.

The invention relates to a method for parking or maneuvering a motor vehicle (10) at low speed, wherein at least one object (30) in the surrounding area of the motor vehicle (10) is detected and used for calculating a target trajectory (20) of the motor vehicle (10), and wherein the motor vehicle (10) is automatically steered in accordance with the target trajectory (20) or the driver of the motor vehicle (10) is provided with corresponding steering instructions. If a minimum distance (dmin) of the motor vehicle (10) to the at least one detected object (30) in the surrounding area is no longer met, the cutting-in radius (r) of the motor vehicle (10) is tracked in accordance with the distance (d) between the motor vehicle (10) and the at least one object (30) in the surrounding area until the distance (d) again exceeds the minimum distance (dmin).

The invention discloses an electric steering control device and method for a walking type electric industrial vehicle. The electric steering control device comprises a steering control vane handle, an electric steering part, a steering processor, a steering control angle sensor and a steering executing angle sensor, wherein the steering control angle sensor is used for sensing a rotating angle X of the steering control vane handle; the steering executing angle sensor is used for sensing a rotating angle Y of the electric steering part; when the steering control vane handle is rotated by an operator, a rotating angle signal is inputted to the steering processor by the steering control angle sensor; the electric steering part is used for receiving a control signal outputted by the steering processor and correspondingly executing the rotating angle Y; the rotating angle Y is changed following the rotating angle X; and a value of Y:X when X is within a preset control resetting angle scope is less than the value of Y:X when X is beyond the control resetting angle scope. The electric steering control device provided by the invention is used for reducing the difficulty in controlling the vehicle to run straightly and preventing a turning radius of the vehicle from being overlarge, thereby forming ideal balance between the straight running and the turning radius.
