Traveling assistant system for vehicles without contact wire
First Claim
1. A traveling assistant system for a vehicle without a contact wire, the traveling assistant system being configured to calculate a velocity pattern in a traveling interval from a current stop station to a next station, the traveling assistant system comprising:
- a memory means which previously stores traveling schedule information of the vehicle, information on the next station located on the traveling interval, and information about a plurality of traffic lights on the traveling interval; and
a velocity pattern calculation means which calculates a velocity pattern of the vehicle based on the traveling schedule information, the information on the next station, and the information about the plurality of the traffic lights,wherein when calculating the velocity pattern in an interval from the current stop station to a first traffic light of the plurality of traffic lights, the velocity pattern calculation means calculates a velocity pattern which satisfies conditions that the vehicle is never stopped at the first traffic light, that the vehicle accelerates at an constant acceleration when the vehicle departs from the current stop station, and that after the acceleration, the vehicle travels at a constant first velocity, andwherein the first velocity is calculated based on a traveling time taken from the current stop station to the first traffic light when the vehicle travels at a maximum velocity, a traveling time taken from the current stop station to the first traffic light calculated considering the traveling schedule information, a traveling distance from the current stop station to the first traffic light, information on the first traffic light, and the constant acceleration.

Abstract
A memory stores traveling schedule information of a vehicle without a contact wire, information on a next station located on a traveling interval and information about a plurality of traffic lights on the traveling interval temporarily, and a velocity pattern calculator for calculating a velocity pattern of the vehicle based on the traveling schedule information, the information on the next station and the information about the plurality of the traffic lights, in which the velocity pattern calculator calculates a velocity pattern which satisfies conditions that the vehicle is never stopped at a first traffic light, that when the vehicle departs from a current stop station, the vehicle is accelerated at an constant acceleration a and that after the acceleration, the vehicle travels at a constant first velocity V1.

20. A traveling assistant system for a vehicle without a contact wire, the traveling assistant system being configured to calculate a velocity pattern in a traveling interval from a current stop station to a next station, the traveling assistant system comprising:
-
a memory means which previously stores traveling schedule information of the vehicle and information on a next station located on the traveling interval; and a velocity pattern calculation means which calculates a velocity pattern of the vehicle based on the traveling schedule information and the information on the next station, wherein when calculating a velocity pattern in an interval between the current stop station and the next station, the velocity pattern calculation means calculates a velocity pattern which satisfies conditions that when the vehicle departs from the current stop station and when the vehicle arrives at the next station, the vehicle is accelerated or decelerated at an constant acceleration, and that the vehicle travels at a constant fourth velocity between acceleration and deceleration, and wherein the fourth velocity is calculated based on a traveling time taken from the current stop station to the next station calculated considering the traveling schedule information, a traveling distance from the current stop station to the next station, and the constant acceleration.
