Abstract

The invention provides a route planning method, system and equipment as well as a storage medium. The method comprises the following steps: determining downhill slope value and downhill slope length of a to-be-determined road section; calculating safe brake total distance of a vehicle for braking on a road surface with the downhill slope value of the to-be-determined road section; judging whetherthe safe brake total distance is smaller than the downhill slope length of the to-be-determined road section; if yes, determining the to-be-determined road section as an avoided road section. With theadoption of the scheme, whether the road section is to be avoided or not is determined by combining the slope angle and the downhill slope length of the to-be-determined road section, so that a safetraveling route is planned; when the method is applied to navigation route planning, safety of each road section in a navigation route can be judged, road sections having the probability of danger areeliminated in advance, the method can also be applied to judgment of safety of the current traveling road section of the vehicle, a driver is reminded to decelerate in advance in case of possible danger, and accordingly, traveling safety of the driver is guaranteed to the greatest extent.

Description

technical field [0001] The present invention relates to the technical field of navigation, in particular to a route planning method, system, device and storage medium. Background technique [0002] In vehicle navigation, path planning is required. The current mainstream path planning schemes are generally based on the starting point, and sometimes refer to vehicle classification (passenger cars, commercial vehicles (trucks), electric vehicles / motorcycles, bicycles, etc.), Through a certain algorithm, a driving path is designed. However, there are some problems in this scheme, the most important of which is: in addition to the height limit, speed limit, and width limit, it is impossible to confirm whether the vehicle can pass this section of road according to the weight and slope of the vehicle, and for this The speed limit of the car. Since the weights of passenger cars are relatively similar and there is not much difference in the upper limit of vehicle weight, this issue...
