Embodiment 1

[0028] see figure 1 , an electric vehicle emergency parking system, the system comprising:

[0029] The battery power detection module is used to detect the remaining power value of the vehicle battery, and transmit the detected remaining power value to the power information judging module;

[0030] The power information judging module is used to receive the remaining power value, and judge the remaining power value and the set power value of the power information judging module. If the remaining power value is less than the set power value, the power information judgment The module generates alarm information and sends it to the alarm module, and the alarm module generates an alarm signal;

[0031] The remaining mileage calculation module is used to receive the remaining power value delivered by the power information judgment module, calculate the maximum mileage that the remaining power can travel through the remaining power value and the power consumption value per kilomet...

Embodiment 2

[0040] This embodiment is optimized as follows on the basis of embodiment 1: the alarm module is an audible and visual alarm module, and the alarm signal is an audio alarm signal and a light alarm signal.

[0041] Compared with Embodiment 1, in order to make the driver pay attention to the power consumption and prevent the driver from not seeing the remaining power of the display screen, in this embodiment, an audible and visual alarm module is connected outside the power information judgment module. When the value is lower than the predetermined value of the power information judging module, the power information judging module sends the information to the audible and visual alarm module, and the alarm module generates an audible and visual alarm signal to remind the driver that the power of the vehicle battery is about to run out.

Embodiment 3

[0043] This embodiment adds the following structure on the basis of embodiment 1 or embodiment 2: the system further includes a detection time control module, which is used to control the battery power detection module to periodically detect the remaining power value.

[0044] In this embodiment, in order to control the detection time of the battery power detection module and reduce the number of detection times to reduce power consumption and module loss, the battery power detection module is also connected to a detection time control module, and the detection time control module controls the battery power detection module. Detection, so that the battery power detection module detects the power situation every other time period.

Abstract

The invention discloses an emergency shutdown system and method for an electric car. The emergency shutdown system comprises a battery electricity detection module, an electric quantity information judgment module, a remaining mileage calculation module, a geographic position memory module, a GPS module, a labeling module, a destination GPS information memory module and a display screen. According to the emergency shutdown system and method for the electric car, the remaining electric quantity condition, the geographic position and the park road segment indication information can be fed back to drivers accurately and timely, the phenomenon that due to the fact that the electricity of the electric car is not enough, the electric car stops on the narrow road or the road section where parking is prohibited can be avoided, the traffic jam can be avoided, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to an emergency parking system and an emergency parking method, in particular to an electric vehicle emergency parking system and method. Background technique [0002] Because most of the power plants are built far away from densely populated cities, there is less harm to human beings, and the power plants are fixed, and the centralized discharge makes it easier to remove various harmful emissions, and related technologies have also been developed. Since electricity can be obtained from a variety of primary energy sources, such as coal, nuclear energy, hydraulic power, etc., people's worries about the depletion of oil resources are relieved. Electric vehicles can also make full use of the surplus electricity when the electricity consumption is low at night to charge, so that the power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Some studies have shown that the same crude oil ...
