Introduction

Accelerating the development of energy-saving vehicles is the key to alleviating fuel supply conflicts, improving air quality, and promoting the healthy and sustainable development of China's automobile industry.

In order to implement the average fuel consumption target for passenger vehicles set out in the “Medium- and Long-Term Development Plan for the Automobile Industry”, China has GB 27999 “Evaluation Methods and Indicators for Passenger Vehicle Fuel Consumption” was promulgated and implemented.

We should prepare the supporting implementation rules of GB 27999 and carry out the energy conservation of off-cycle technologies/devices for passenger vehicles based on the principle of encouraging advanced and quantifiable evaluation.

The work of formulating the energy effect evaluation method.

In view of the differences in technical principles, energy-saving effects and application levels of different off-cycle technologies/devices, the evaluation methods of energy-saving effects are also different.

There are differences, so GB/T 40711 "Evaluation Method for Energy Saving Effect of Passenger Car Off-cycle Technology/Equipment" is compiled into a partial document.

Based on the industry management needs and technical application characteristics, we have developed a gear shift reminder device, idle start-stop system, car air conditioning, and brake energy recovery system.

At the same time, the possibility of expanding to include other non-circulation technologies/devices in the future is not ruled out.

GB/T 40711 is proposed to consist of seven parts.

— Part 1: Gear shift reminder device. The purpose is to determine the out-of-cycle energy saving effect evaluation method of the gear shift reminder device of a passenger car.

— Part 2: Idle start-stop system. The purpose is to determine the off-cycle energy-saving effect evaluation method of the idle start-stop system of passenger cars.

— Part 3: Automobile air conditioning. The purpose is to determine the evaluation method of the energy saving effect of the air conditioning of passenger cars outside the cycle.

— Part 4: Braking energy recovery system. The purpose is to determine the energy saving effect of the braking energy recovery system of passenger vehicles outside the cycle Price method.

— Part 5: Generator. The purpose is to determine the evaluation method of the off-cycle energy saving effect of the generator of a passenger car.

— Part 6: Active airflow control system in the vehicle. The purpose is to determine the circulation of active airflow control system in passenger cars.

Energy effect evaluation method.

— Part 7: Predictive energy management system. The purpose is to determine the off-cycle energy saving effect evaluation of the predictive energy management system for passenger vehicles. Price method.

Each technology/device energy saving effect evaluation method is a part of GB/T 40711, and each part complements each other and together constitutes our In the future, the standard system of off-cycle technology/device will be further adjusted and improved according to the development of the industry.

system, and promote the advancement of energy-saving technology in the industry.
