Vehicle and power supply system of vehicle

Abstract

A vehicle includes an ADK that creates a driving plan, a VP that carries out vehicle control in accordance with various commands from the ADK, and a vehicle control interface that interfaces between the VP and the ADK. A power supply structure for the ADK is provided independently of a power supply structure for the VP.

         1 . A vehicle comprising:
 an autonomous driving system that creates a driving plan;   a vehicle platform that carries out vehicle control in accordance with an instruction from the autonomous driving system; and   a vehicle control interface box that interfaces between the vehicle platform and the autonomous driving system, wherein   the autonomous driving system includes a power supply structure independently of a power supply structure for the vehicle platform.   
     
     
         2 . The vehicle according to  claim 1 , wherein
 the vehicle platform includes
 a high-voltage battery, 
 a first primary power supply system that receives supply of electric power from the high-voltage battery, and 
 a first secondary power supply system as a redundant power supply for the vehicle platform, and 
   the autonomous driving system includes
 a second primary power supply system that receives supply of electric power from the high-voltage battery, and 
 a second secondary power supply system as a redundant power supply for the autonomous driving system. 
   
     
     
         3 . The vehicle according to  claim 2 , wherein
 when a power feed function of the first primary power supply system fails, the first secondary power supply system keeps for a certain time period, feeding power to a limited system of systems that configure the vehicle platform.   
     
     
         4 . The vehicle according to  claim 3 , wherein
 the limited system includes a brake system, a steering system, and a vehicle immobilization system.   
     
     
         5 . The vehicle according to  claim 2 , wherein
 when a power feed function of the first primary power supply system fails, the first secondary power supply system keeps feeding power to the vehicle control interface box.   
     
     
         6 . The vehicle according to  claim 2 , wherein
 the first primary power supply system includes
 a DC/DC converter that subjects electric power from the high-voltage battery to voltage conversion, and 
 an auxiliary battery connected to an output of the DC/DC converter, 
   the first secondary power supply system includes
 a switching DC/DC converter connected to the output of the DC/DC converter, and 
 a secondary battery connected to an output of the switching DC/DC converter, and 
   when a power feed function of the first primary power supply system fails, the switching DC/DC converter electrically disconnects the secondary battery from the first primary power supply system.   
     
     
         7 . A power supply system of a vehicle, the vehicle including an autonomous driving system that creates a driving plan, a vehicle platform that carries out vehicle control in accordance with an instruction from the autonomous driving system, and a vehicle control interface box that interfaces between the vehicle platform and the autonomous driving system, the power supply system comprising:
 a first power supply system that implements a power supply of the vehicle platform; and   a second power supply system that implements a power supply of the autonomous driving system,   the second power supply system being provided independently of the first power supply system.   
     
     
         8 . The power supply system of the vehicle according to  claim 7 , wherein
 the first power supply system includes
 a high-voltage battery, 
 a first primary power supply system that receives supply of electric power from the high-voltage battery, and 
 a first secondary power supply system as a redundant power supply for the vehicle platform, and 
   the second power supply system includes
 a second primary power supply system that receives supply of electric power from the high-voltage battery, and 
 a second secondary power supply system as a redundant power supply for the autonomous driving system. 
   
     
     
         9 . The power supply system of the vehicle according to  claim 8 , wherein
 when a power feed function of the first primary power supply system fails, the first secondary power supply system keeps for a certain time period, feeding power to a limited system of systems that configure the vehicle platform.   
     
     
         10 . The power supply system of the vehicle according to  claim 9 , wherein
 the limited system includes a brake system, a steering system, and a vehicle immobilization system.   
     
     
         11 . The power supply system of the vehicle according to  claim 8 , wherein
 when a power feed function of the first primary power supply system fails, the first secondary power supply system keeps feeding power to the vehicle control interface box.   
     
     
         12 . The power supply system of the vehicle according to  claim 8 , wherein
 the first primary power supply system includes
 a DC/DC converter that subjects electric power from the high-voltage battery to voltage conversion, and 
 an auxiliary battery connected to an output of the DC/DC converter, 
   the first secondary power supply system includes
 a switching DC/DC converter connected to the output of the DC/DC converter, and 
 a secondary battery connected to an output of the switching DC/DC converter, and 
   when a power feed function of the first primary power supply system fails, the switching DC/DC converter electrically disconnects the secondary battery from the first primary power supply system.
