Problems solved by technology

[0004] For example, when the vehicle is driving on a plateau, the actual power of the engine will decrease due to factors such as rising altitude, thin air, and decreased oxygen content. Accurately grasp the driving status of the vehicle

Embodiment 1

[0022] Such as figure 1 As shown, the framework of the vehicle cruise speed reduction prompt system of the present invention includes: a cruise button, an integrated electronic parking brake system, an adaptive cruise controller assembly and a combined instrument assembly. The driver sets the vehicle speed through the cruise button according to the demand, and the button sends the set speed signal to the cruise system, and the cruise system compares it with the vehicle speed signal sent by the integrated electronic parking brake system; the cruise system monitors its own cruise status, Information such as speed difference and vehicle target in front judges whether it is affected by a specific road and has not reached the set state. In order to ensure that the driver can control the vehicle status in real time, the cruise system sends a display demand signal to the instrument cluster assembly, and the instrument assembly pops up a text box prompt driver.

Embodiment 2

[0024] Utilize the system described in embodiment 1 to carry out the method for vehicle cruising speed reduction prompt as follows:

[0025] 1. The system judges the cruise mode status, the cruise system is activated and the radar detects no target vehicle ahead;

[0026] 2. Subtract the cruising set speed of 120km / h from the current speed of 80km / h issued by the integrated electronic parking system to obtain a differential vehicle speed X=40km / h, and compare it with the differential vehicle speed N calibrated by the system. The value vehicle speed X=40km / h is greater than the differential vehicle speed N=10km / h calibrated by the system, assign the current differential vehicle speed value X=40km / h to Y, and Y=40km / h.

[0027] 3. The cruise system judges whether the current variable speed X meets the condition: (Y-A)

[0028] 4. When the above conditions are me...

Abstract

The invention provides a vehicle cruise deceleration prompting method and system, and the overall scheme is that a cruise system compares a cruise set vehicle speed with a vehicle speed signal transmitted by an integrated electronic parking brake system when a vehicle in a cruise mode and there is no target vehicle at the front; when it is monitored that the speed difference between the two does not reach the set state, the cruise system sends a display demand signal to a combination instrument assembly, and the combination instrument assembly sends prompt information to remind a driver. According to the technical scheme, logic judgment can be conducted on the current driving state through the cruise system, the driver is prompted through characters, and the purposes of prompting the driver to pay attention to the vehicle state and protecting the normal driving safety of the driver when the vehicle power is insufficient due to special road conditions are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile information processing and display, in particular to a display scheme for using an adaptive cruise controller assembly and a combined instrument assembly for cruising and slowing down in some usage scenarios. Background technique [0002] The adaptive cruise system is an essential system in vehicles with automatic assisted driving. The adaptive cruise system usually detects the vehicle in front through the millimeter-wave radar, and controls the vehicle to drive at the set speed; when the vehicle in front is lower than the set speed of the vehicle, the control The vehicle follows the vehicle in front, stops and starts following the vehicle in front, frees the driver's feet under appropriate road conditions, and relieves the driver's fatigue. [0003] With the increase in the penetration rate of self-driving cars, from developed cities with better road conditions to remote areas with poor road c...
