Claim 11:
12. A self-driving safety evaluation apparatus comprising:
a memory configured to store program instructions; and
a processor coupled to the memory, wherein the program instructions cause the processor to be configured to:
obtain, based on environment data sensed by a sensor mounted on a vehicle, rb and rc, wherein rb is a first risk value of the vehicle in a shadow driving mode in a first measurement unit, wherein rc is a second risk value of the vehicle in a self-driving mode based on a preset route in the first measurement unit, wherein the shadow driving mode is a self-driving mode of the vehicle based on a real-time route, wherein the real-time route is predicted and continuously modified based on a location and a movement parameter of the vehicle in a manual driving mode, and wherein the first measurement unit is a time period or a distance;
determine RB based on rb, wherein RB is a third risk value of the vehicle in the shadow driving mode in a plurality of measurement units, and wherein the measurement units comprise the first measurement unit;
determine RC based on rc, wherein RC is a fourth risk value of the vehicle in the self-driving mode based on the preset route in the measurement units, and wherein RB and RC are used to determine whether a safety of the vehicle in a self-driving route meets a requirement, wherein the requirement comprises the sum of RB and RC is less than or equal to a self-driving risk threshold, wherein the self-driving risk threshold is a(RA+R′A), wherein a is a risk tolerance coefficient, wherein RA is a fifth risk value of the vehicle in the manual driving mode in the measurement units, wherein a road section through which the vehicle passes in the measurement units is a first road section, and wherein R′A is a sixth risk value of the vehicle passing through the first road section outside the measurement units based on the manual driving mode;
calculate a sum of RB and RC;
send, to a cloud device coupled to the processor via a communication interface, the sum of RB and RC to determine whether that the safety of the vehicle on the self-driving route meet the requirement; and
control the vehicle to travel on the self-driving route when determining the safety of the vehicle on the self-driving route meet the requirement.
