Abstract

The invention relates to a gear shifting prompting method and a gear shifting prompting system and belongs to the technical field of control of engines. The gear shifting prompting method comprises the following steps: (1) at least collecting speed, rotating speed, engine load rate and gear information of a current vehicle; and (2) judging the engine load rate and executing the following steps according to the engine load rate: a, if the engine load rate is greater than a set high value, not prompting or prompting downshift; b, if the engine load rate is smaller than a set low value, promptingupshift; and c, if the engine load rate is greater than or equal to the set low value but smaller than or equal to the set high value, not prompting. By judging the engine load rate to prompt gears of the vehicle intelligent, a problem that the condition that the vehicle is short of power and potential safety hazards are easily caused as the rotating speed is limited when the vehicle needs relatively high power is avoided.

Description

technical field

[0001] The invention relates to a gear shift prompt method and system, belonging to the technical field of engine control. Background technique

[0002] In the process of driving a vehicle, drivers often have bad driving behaviors such as rapid acceleration, rapid deceleration, or high-speed low-speed driving. These bad driving behaviors will have a greater impact on the energy consumption of the vehicle. According to the comparison of relevant research data , Bad driving behavior can have an impact of up to 20-30% on the energy consumption performance of the vehicle. Reducing or avoiding bad driving behavior is of great significance to the energy consumption performance of the whole vehicle. Generally, the bad driving behavior of drivers can be reduced to a certain extent by providing energy-saving driving training for drivers or installing energy-saving driving reminder devices on vehicles, but Can not fundamentally solve the above-mentioned problem.
