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 a cable laying side pressure monitor and belongs to the technical field of cable laying equipment. The cable laying side pressure monitor comprises a signal collection mechanism and a signal processing mechanism, wherein the signal collection mechanism comprises a pressure sensor; the pressure sensor is mounted on a base on which the lateral idler wheel of a turning pulley is positioned; the signal processing mechanism comprises a signal processing device, a signal outputting device and a power supply which are connected with one another; and the pressure sensor is electrically connected with the signal processing device. The invention further discloses a cable turning pulley; and the cable laying side pressure monitor is mounted on the cable turning pulley base. The technical scheme is as follows: the pressure sensor arranged on the cable turning pulley base can monitor the lateral pressure of a cable in real time; and meanwhile, a detector has an automatic alarming function when the lateral pressure is too great. Illegal operation in a cable laying process can be avoided, the cable laying quality is improved and the cable fault rate is reduced; and the economic loss caused by the quality problem of laying construction is reduced, and the safe and stable operation of a high-voltage cable is guaranteed.

The present invention provides a system for bus left-turn regulation and control of a left-turn and straight common signal lamp crossroad. The system comprises: a vehicle signal sender arranged on the bus which turns the left at the crossroad; and signal receivers arranged at four corners of the crossroad. The vehicle signal sender is configured to emit left-turn signals when the bus turns left; the signal receivers are connected with a traffic light controller of the crossroad and configured to receive the left-turn signals and send the left-turn signals to the traffic light controller, and the traffic light controller controls the state of the traffic light according to the current state of the traffic light. The system and method for bus left-turn regulation and control of the left-turn and straight common signal lamp crossroad can improve the left-turn efficiency of the bus at the crossroad to the utmost extent so as to reduce the influence on the straight vehicles to a minimum.

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.
