CONTROL SYSTEM AND SEMICONDUCTOR DEVICE
First Claim
1. A control system comprising:
- a first storage unit that stores a plurality of pieces of data indicating, in association with each other, a factor that occurs with respect to a vehicle and control contents of the vehicle to be performed with respect to the factor;
a second storage unit that can be accessed at a higher speed than the first storage unit, and that stores a smaller number of pieces of data than the number of pieces of data stored in the first storage unit;
an estimating unit that estimates the factor and a required time until encountering the factor based on a result of an observation of a periphery of the vehicle; and
a deciding unit that decides control contents of the vehicle based on the estimated factor and the data, whereinwhen the estimated required time is longer than a threshold, the deciding unit decides control contents of the vehicle based on data stored in the first storage unit, andwhen the estimated required time is equal to or shorter than the threshold, the deciding unit decides control contents of the vehicle based on data stored in the second storage unit.

Abstract
An object of the present invention is to control a vehicle with less delay. A control system 100 according to the present invention includes: an estimating unit 103 that estimates a factor and a required time until encountering the factor based on a result of an observation of a periphery of a vehicle; and a deciding unit 104 that decides control contents of the vehicle based on data stored in a first storage unit 101 when the required time is longer than a threshold and that decides control contents of the vehicle based on data stored in a second storage unit 102 which can be accessed at a higher speed than the first storage unit 101 when the required time is equal to or shorter than the threshold.

13. A semiconductor device comprising:
-
an estimating unit that estimates, based on a result of an observation of a periphery of a vehicle, a factor which occurs with respect to the vehicle and a required time until encountering the factor; and a presenting unit that acquires control contents based on the estimated factor from a first storage unit which stores a plurality of pieces of data indicating, in association with each other, the factor and control contents of the vehicle to be performed with respect to the factor, and a second storage unit which can be accessed at a higher speed than the first storage unit and which stores a smaller number of pieces of data than the number of pieces of data stored in the first storage unit, and that presents the acquired control contents as a candidate of control contents of the vehicle to another semiconductor device that controls the vehicle, wherein the presenting unit; acquires the control contents from the first storage unit and presents the acquired control contents to the other semiconductor device when the estimated required time is longer than a threshold; and acquires the control contents from the second storage unit and presents the acquired control contents to the other semiconductor device when the estimated required time is equal to or shorter than the threshold.

14. A semiconductor device comprising
a control unit that acquires control contents based on a factor which occurs with respect to a vehicle and that decides control contents of the vehicle, from a first storage unit which stores a plurality of pieces of data indicating, in association with each other, a factor that occurs with respect to the vehicle and control contents of the vehicle to be performed with respect to the factor, and from a second storage unit which can be accessed at a higher speed than the first storage unit and which stores a smaller number of pieces of data than the number of pieces of data stored in the first storage unit, wherein the control unit: -
decides the control contents of the vehicle from the control contents acquired from the first storage unit when a required time until encountering the factor as acquired from another semiconductor device is longer than a threshold; and decides the control contents of the vehicle from the control contents acquired from the second storage unit when the required time is equal to or shorter than the threshold.
