Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle monitoring, and in particular to an anti-idling system for new energy vehicles. Background Art

[0002] With growing global awareness of environmental protection and the energy crisis, the research, development, and application of new energy vehicles (EVs) are gaining increasing attention. With their zero-emissions and low energy consumption advantages, NEVs have become a mainstream trend in the automotive industry's transformation. The high torque of their electric motors in NEVs can lead to tire spin and slippage. This phenomenon is particularly pronounced in complex road conditions, especially in rainy and snowy conditions. Slippage prevents the tires from generating sufficient friction with the road surface, making the vehicle susceptible to malfunction during acceleration and braking. Summary of the Invention

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0020] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] See also Figure 1-2 , an anti-idling system for new energy vehicles, comprising:

[0022] Speed ​​sensor, installed at the wheel axle of new energy vehicles, used to collect wheel speed;

[0023] The control microcomputer is connected to the speed sensor and the motor driver respectively. When the wheel speed exceeds a set threshold within a preset time, the wheel slips and the control microcomputer reduces the output power of the motor driver; the motor driver is used to drive the wheel to operate.

[0024] The control microcomputer is connected to the electric brake pump. When the wheel speed exceeds a set threshold within a preset time, the control microcomputer controls the electric brake pump to brake.

[0025] The communication network module is connected to the control microcomputer and is used to receive information sent by the host computer.

[0026] During the operation of new energy vehicles, the wheel speed changes in a relatively smooth curve. When the motor is output, the speed will change in a smooth rising curve or remain unchanged. If the collected speed suddenly increases, it means that the wheel is spinning. In this case, the output power will be reduced and the brakes can be applied to a stable speed state, and this information will be uploaded to the host computer. If the platform receives a certain amount of wheel slip and spinning information within the specified time period, it will designate this section of road as a section prone to slip and send a warning instruction to all cars that may enter this section of road.

[0027] In the embodiment of the present invention, a sensor is added to the wheel axle to measure its rotational speed and transmit the data to the microcomputer. When the new energy vehicle is in operation, if the wheel speed increases suddenly, the microcomputer controls to reduce the motor output power and apply the brake, and compares it with the curve during this period until the speed returns to a smooth speed curve. Here, we take five speed values ​​within 1s as an example, and take a speed value every 20ms, which are set as A, B, C, D, and E respectively; put it into the formula The system then determines the wheel is slipping and spinning if W > KC within a limited range. This slip information is uploaded to the new energy vehicle supervision platform for accumulation (here, three slips within 30 minutes are used as an example). After three slips within 30 minutes, the platform analyzes each new energy vehicle's common routes based on the platform's recorded routes. Alternatively, it analyzes traffic flow at nearby intersections to identify vehicles likely to pass through this section of road. This system then issues a warning to vehicles likely to pass through this intersection: The road ahead is prone to slipping on the XX section. Please drive smoothly.

[0028] According to the specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0029] The present invention can reduce the risk of accidents caused by skidding by monitoring the wheel speed in real time and adjusting it through a control microcomputer, thereby improving the driving safety of the vehicle.
