Problems solved by technology

During the driving process of the car, in order to make the gear change of the vehicle adapt to the current road environment, it is necessary to perform the gear change according to the road conditions in real time during driving, so that the gears are coordinated with the road conditions. Only the gears that meet the road conditions Changing can increase the driv...

Embodiment Construction

[0072] The present invention provides a gear shifting method based on road parameters. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0073] The details are as follows:

[0074] Such as figure 1 and Figure 21 As shown, the present invention mainly completes the following three functions: map matching (matching the positioning data output by the GPS receiver with the electronic map to determine the vehicle position), road parameter pre-reading (reading out relevant road parameters in advance) and based on Gear shifting of road parameters (gear shifting is performed according to road parameters).

[0075] map matching

[0076] A complete map matching algorithm includes three processes: determine the ...

Abstract

The invention discloses a gear shifting method based on road parameters. The gear shifting method comprises the following steps of enabling positioning data outputted by a GPS receiver of an automobile to be matched with an electronic map so as to determine the position and a running route of the automobile, enabling road parameters to be matched with the gear of the automobile, and shifting the gear of the automobile according to specific road parameters; then enabling the positioning data outputted by the GPS receiver to be matched with the data of the electronic map so as to determine the specific position of the automobile on roads, and based on the position, acquiring environmental parameters of the current road in a real time manner; and according to the parameters, adjusting gear shifting parameters, so that the gear shifting is more suitable for the current road environment, and the adaptability of the gear shifting to the road environment is strengthened. Comfortable and safe driving environment is provided for people, and the power performance and the economic efficiency of the automobile are improved. A gear shifting method under different road conditions is treated, so that the automobile can well meet gear shifting requirements under different slope-road conditions.

Description

technical field [0001] The invention relates to the field of automatic gear shifting of vehicles, in particular to a gear shifting method based on road parameters. Background technique [0002] With the development of automobile technology, automatic vehicle transformation technology (AT and AMT are widely used) has been widely used. Although the automatic gear shift reduces the driving burden to a certain extent, people also put forward higher and higher requirements for the comfort, power and economy of car driving at the same time. During the driving process of the car, in order to make the gear change of the vehicle adapt to the current road environment, it is necessary to perform the gear change according to the road conditions in real time during driving, so that the gears are coordinated with the road conditions. Only the gears that meet the road conditions Changing can increase the driving comfort of the vehicle and improve the power and economy. However, the gear s...
