Abstract

Acceleration data is received for each of a plurality of times t 1 . . . t n , from one or more components in a host vehicle. A traffic jam assist (TJA) system is based on the acceleration data, thereby actuating one or more of steering, braking, and propulsion.

First claim

What is claimed is:

1 . A method, comprising:
receiving acceleration data, for each of a plurality of times t 1 . . . t n , from one or more components in a host vehicle; and activating a traffic jam assist (TJA) system based on the acceleration data, thereby actuating one or more of steering, braking, and propulsion.

2 . The method of claim 1 , wherein the one or more components include the propulsion and braking.

3 . The method of claim 2 , wherein receiving the acceleration data from the one or more components includes receiving data from each of the propulsion and the braking.

4 . The method of claim 3 , wherein the acceleration data includes a positive acceleration at one of the times and a negative acceleration at another of the times.

5 . The method of claim 1 , further comprising receiving data from a remote source that is one of a second vehicle and a computer outside the host vehicle indicating a traffic jam, wherein activating the TJA is based on the data from the remote source in addition to the data from one or more components in the host vehicle.

6 . The method of claim 1 , further comprising detecting a second vehicle proximate to the host vehicle, wherein activating the TJA is further based on detecting the second vehicle proximate to the host vehicle.

7 . The method of claim 6 , wherein detecting the second vehicle proximate to the host vehicle includes detecting a plurality of distances of the second vehicle from the host vehicle.

8 . The method of claim 6 , further comprising detecting a third vehicle proximate to the host vehicle, wherein activating the TJA is further based on detecting the third vehicle proximate to the host vehicle.

9 . A computer, comprising a processor and a memory, the memory storing instructions executable by the processor to:
receive acceleration data, for each of a plurality of times t 1 . . . t n , from one or more components in a host vehicle; and activate a traffic jam assist (TJA) system based on the acceleration data, thereby actuating one or more of steering, braking, and propulsion.

10 . The computer of claim 9 , wherein the one or more components include the vehicle propulsion and braking.

11 . The computer of claim 10 , wherein instructions to receive the acceleration data from the one or more components include instructions to receive data from each of the propulsion and the braking.

12 . The computer of claim 9 , wherein the acceleration data includes a positive acceleration at one of the times and a negative acceleration at another of the times.

13 . The computer of claim 9 , the memory of the computer storing further instructions to receive data from a remote source that is one of a second vehicle and a second computer outside the host vehicle indicating a traffic jam, wherein activating the TJA is based on the data from the remote source in addition to the data from one or more components in the host vehicle.

14 . The computer of claim 9 , the memory of the computer storing further instructions to detect a second vehicle proximate to the host vehicle, wherein activating the TJA is further based on detecting the second vehicle proximate to the host vehicle.

15 . The computer of claim 14 , wherein instructions to detect the second vehicle proximate to the host vehicle include instructions to detect a plurality of distances of the second vehicle from the host vehicle.

16 . The computer of claim 14 , the memory of the computer storing further instructions to detect a third vehicle proximate to the host vehicle, wherein activating the TJA is further based on detecting the third vehicle proximate to the host vehicle.

17 . A system, comprising:
a vehicle communication network; a traffic jam assist (TJA) system communicatively coupled to the vehicle communication network; and a computer that is communicatively coupled to the vehicle communication network and that includes a processor and a memory, the memory storing instructions executable by the processor to receive acceleration data, for each of a plurality of times t 1 . . . t n , from one or more components in a host vehicle, and provide a command to activate the (TJA) system based on the acceleration data, thereby actuating one or more of steering, braking, and propulsion.

18 . The system of claim 17 , wherein the one or more components include the vehicle propulsion and braking.

19 . The system of claim 17 , wherein the acceleration data includes a positive acceleration at one of the times and a negative acceleration at another of the times.

20 . The system of claim 17 , the memory of the computer storing further instructions to detect a second vehicle proximate to the host vehicle, wherein activating the TJA is further based on detecting the second vehicle proximate to the host vehicle
