-during a detection task, detecting a current position (P) of said toy vehicle (T) and calculating a vehicle speed (V) from said current position (P), based on an initial position (O) of said toy vehicle determined by said position sensor (S);
If the current position (P) and the calculated vehicle speed (V) satisfy a stop detection condition (C1), ending the detection task and determining a target position for the toy vehicle to travel forward (D1);
controlling the drive circuit (D) so that the toy vehicle (T) travels forward and stops at the target position (D1);
if it is determined that the toy vehicle (T) has reached and stopped at a target position (D1), the drive circuit (D) is controlled so that the toy vehicle (T) is reversed to the initial position (O) and stopped at the initial position (O).
The microcontroller (C) is configured to: controlling the drive circuit (D) to set the calculated vehicle speed (V) as an initial speed control target for forward travel or to set the opposite of the calculated vehicle speed (V) as an initial speed control target for reverse travel.
The microcontroller (C) is configured to: if the detected current position (P) is less than a back-off threshold (TH 2), the detection is returned directly after controlling the drive circuit (D) so that the toy vehicle (T) is driven forward and stopped at the target position (D1) instead of reversing the toy vehicle (T) to the initial position (O).
The stop detection condition (C1) is that the current position (P) is greater than a forward threshold (TH 1), or the stop detection condition (C1) is that the current position (P) is less than a reverse threshold (TH 2), or the stop detection condition (C1) is that the calculated vehicle speed (V) reaches a speed maximum.
The position sensor (S) comprises an orthogonal rotary encoder consisting of a Hall encoding magnet and a Hall sensor, an orthogonal rotary encoder consisting of a grating and an optical transceiver, or an optical mouse sensor.
The control method for the toy vehicle (T) described above comprises the following steps:
a) during a detection task, determining an initial position (O) of the toy vehicle (T), detecting a current position (P) of the toy vehicle (T) and calculating a vehicle speed (V) from the current position (P);
b) if the current position (P) and the calculated vehicle speed (V) satisfy a stop detection condition (C1), ending the detection task and determining a target position for the toy vehicle to travel forward (D1);
c) controlling the toy vehicle (T) to travel forward and stop at the target position (D1);
d) controlling the toy vehicle (T) to reverse to the initial position (O) and stop at the initial position (O) if it is determined that the toy vehicle (T) has reached and stopped at the target position (D1);
e) Re-entering step a).
The vehicle speed (V) calculated in step a) is used in step c) as an initial speed control target for forward travel.
In step d) the inverse of the vehicle speed (V) calculated in step a) is used as an initial speed control target for reversing.
If the current position (P) detected at step a) is less than a back-off threshold (TH 2), then step d) is not performed after step c), and step e) is entered directly.
In use, a toy vehicle (T) determines an initial position (O) of the toy vehicle based on a position sensor (S), and when pushing the toy vehicle (T) forward, detects a current position (P) of the toy vehicle (T) and calculates a vehicle speed (V) based on the current position (P), and determines a target position (D1) at which the toy vehicle is traveling forward; controlling the drive circuit (D) so that the toy vehicle (T) travels forward and stops at the target position (D1); then controlling the drive circuit (D) to reverse the toy vehicle (T) to the initial position (O) and stop at the initial position (O).

The specific usage scenario may be: the toy vehicle (T) is pushed forward by the child, when the toy vehicle (T) is pushed forward beyond a certain distance (TH 1) (corresponding to one possible stop detection condition C1), or the vehicle speed of the toy vehicle is reduced from the maximum (corresponding to another possible stop detection condition C1), the toy vehicle is electrically propelled, the vehicle speed is controlled to run forward with the goal of stopping at D1, and thereafter, the toy vehicle (T)
It reverses itself back to the starting position (position O). So that the child can continue playing the car. The force of pushing the baby forward is the same, the distance and the speed of the baby carriage are different, and good interactive experience is achieved. The vehicle can back to the initial position (O) by itself, which increases the novelty and is convenient to initiate the next pushing.
In addition, the vehicle can also simulate the effect of the traditional return vehicle. Different from the traditional return vehicle, the vehicle is controlled by the controller in the forward running process, so that more behavior changes are conveniently realized, and the richness of interaction is increased.

Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
