A car eco-driving state prompt system and prompt method

Abstract

The invention discloses an automobile ECO driving state prompt system and a prompt method. The prompt system includes a clutch pedal sensor, a brake pedal sensor, an accelerator pedal sensor, an engine speed sensor, a vehicle speed sensor, an engine control unit, an electronic body stability controller, Body controller and instruments; engine control unit is connected with clutch pedal sensor, brake pedal sensor, accelerator pedal sensor, engine speed sensor, and connected with body controller through CAN bus; electronic body stability controller is connected with vehicle speed sensor, and connected with The CAN bus is connected to the body controller; the body controller is connected to the instrument through the CAN bus. The prompting method is as follows: calculating the gear position information and fuel consumption information according to the acquired signal, calculating the ECO degree of no-load, half-load and full-load states, and judging whether it is an ECO state, and displaying it. It can more accurately prompt the current vehicle's ECO degree and whether it is in an ECO state.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an automobile ECO driving state prompting system and a prompting method, which are used for prompting whether the automobile is currently in a fuel economy mode. Background technique [0002] The automobile industry is an important pillar industry of the national economy and plays an important role in the development of the national economy and society. With my country's sustained and rapid economic development and accelerated urbanization, the demand for automobiles will continue to grow for a long period of time in the future, and the resulting energy shortage and environmental pollution will become more prominent. Accelerating the cultivation and development of energy-saving vehicles and new energy vehicles is not only an urgent task to effectively alleviate energy and environmental pressure and promote the sustainable development of the automobile indus...

[0006] The existing patent with publication number CN101983143A discloses an ECO driving assistance device, an ECO driving assistance information generating device, an ECO driving assistance information computing device, an ECO driving status display device, an ECO driving assistance system, and an ECO driving assistance information computing method , to prompt the ECO driving status. In this patent, the ECO driving assistance device displays on the indicator panel the information used to assist ECO driving generated by the execution of the instrument electronic control unit (that is, the instrument ECU). information such as speed, vehicle speed, gear position, and switch for changing the control mode of the vehicle, generate information for determining whether the vehicle is in the ECO driving state, and switch the display for the ECO driving state; since the gear in the ECO driving assistance device The position information comes from the gear position sensor, so it is only applicable to AT / AMT / IMT vehicles, not applicable to MT (manual transmission) vehicles (because MT vehicles do not have a gear position sensor), adding a gear position sensor will increase the cost; In addition, the fuel consumption value of the vehicle is different under no-load, half-load and full-load, and the fuel consumption value must be compared and judged according to the pre-calibrated no-load economic fuel consumption MAP map, half-load economic fuel consumption MAP map and full-load economic fuel consumption MAP map Whether it is economical fuel consumption to ensure the accuracy of the calculated ECO degree and the judgment of whether it is in the ECO state; and the above-mentioned patent does not make this comparative judgment, and its accuracy is not high
