Embodiment 1

[0050] like figure 1 As shown, the embodiment of the present invention provides a driving assistance method, which includes:

[0051] In step 101, a driving assistance activation signal is received, and the driving assistance activation signal is sent by a driver.

[0052] In the embodiment of the present invention, if the driver is not proficient in driving skills and drives through a road section with poor road conditions, or the driver feels tired, a signal to activate the assisted driving can be issued to activate the assisted driving.

[0053] In step 102, the velocity and acceleration of the first cycle of the vehicle are collected.

[0054] In the embodiment of the present invention, the speed and acceleration of the car are collected in a cycle of 0.01s, and the speed and acceleration of each cycle are used as the speed and acceleration of the first cycle to obtain the speed and acceleration of the second cycle of the car.

[0055] In step 103, according to the speed...

Embodiment 2

[0063] like Image 6 As shown, the embodiment of the present invention provides a driving assistance method, which includes:

[0064] In step 201, a driving assistance activation signal is received, and the driving assistance activation signal is sent by the driver.

[0065] In the embodiment of the present invention, if the driver is not proficient in driving skills and drives through a road section with poor road conditions, or the driver feels tired, a signal to activate the assisted driving can be issued to activate the assisted driving.

[0066] When the assisted driving signal is generated, the driver no longer takes any driving action, and when the driver makes a driving action again, the assisted driving process stops.

[0067] In step 202, the velocity and acceleration of the first cycle of the vehicle are collected.

[0068] In the embodiment of the present invention, the speed and acceleration of the car are collected in a cycle of 0.01s, and the speed and acceler...

Embodiment 3

[0083] like image 3 As shown, the embodiment of the present invention provides a driving assistance system, which includes:

[0084] The switch control module 1 is used to receive the start auxiliary driving signal, the start auxiliary driving signal is sent by the driver, and the start auxiliary driving signal is sent to the switch control module 1;

[0085] The information collection module 2 is used to collect the speed and acceleration of the first cycle of the automobile;

[0086] The data processing module 3 is used to obtain the acceleration, accelerator opening and braking torque of the second cycle of the car according to the speed and acceleration of the first cycle of the car and the preset threshold value of the speed difference between the first cycle and the second cycle;

[0087] The driving control module 4 is configured to control the accelerator of the vehicle according to the accelerator opening of the second period and / or control the gearbox of the vehicl...

Abstract

The invention discloses an auxiliary driving method, an auxiliary driving system and a vehicle, and belongs to the field of vehicles. The auxiliary driving system comprises a switch control module, an information collection module, a data processing module and an accelerator control module. The information collection module collects the speed and the accelerated velocity of the vehicle at the first cycle, the data processing module obtains the accelerated velocity, the accelerator opening and braking torque of the vehicle at the second cycle according to the speed and the accelerated velocity of the vehicle at the first cycle, as well as the speed difference threshold between the first cycle and the second cycle, a driving control module controls an accelerator of the vehicle according to the accelerator opening at the second cycle and/or controls a gearbox according to the braking torque at the second cycle, so that when the vehicle runs on a section with poor pavement conditions, auxiliary driving is started if a driver is unskillful in driving or at an exhausted state, the vehicle can be guaranteed to run stably, further the comfort of passengers is guaranteed, and damage to parts of the vehicle due to vibration of the vehicle body is avoided.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an auxiliary driving method, an auxiliary driving system and an automobile. Background technique [0002] Acceleration and braking are required to be used together during car driving, especially when the road conditions are bad, and the driver is required to switch between accelerator and brake flexibly. However, if the driver is not skilled enough or is tired, When the car encounters an obstacle, it is very easy to fail to pass the obstacle due to improper throttle control or jump forward several meters after passing the obstacle. Contents of the invention [0003] In order to solve the problem in the prior art that if the driver's driving skills are not skilled enough or in a tired state, when the car encounters an obstacle, it is very easy to fail to pass through the obstacle due to improper throttle control or jump forward several times after passing through the obstacle. In vie...
