Automatically Commanded Steering Functions | Session 4 | 25-27 Nov 2015
Tokyo
Agenda Item 5.8.
Document ACSF-04-07

Main content of document from (D):
Purpose of this document is to describe manoeuvres to minimize the risk in case the driver does not take over steering

(all): The delegates confirmed, the in future the name of MRM is: Minimal Risk Manoeuvre
(D): This is a bundle of tests, and we should select, which tests is necessary
(SE): Appropriate test tracks have normally an inclination, was this considered?
(D): No, to perform the test a test track with minimum inclination should be used. Also an adjustment in the speed could solve this issue.
(OICA): How does the table (page 11) shall justify the 3m/s²?
(D): The table should show, that with 3m/s² we are on the safe side.

(D): TR3: Lane change is not mandated, also stopping is possible.

(OICA): In CAT A-C systems are always in responsibility of the driver.
(D): For transition demand and MRM it is needed
(OICA): If the MRM has to be performed in failure conditions too, this would then be a level 4 system. – We should consider, that the driver is still in the loop.
(D): We have the choice to select the tests which seem to be necessary
(Chair): This depends on the Driver Recognition System. If this works quite well, tests may be obsolete.
(SE): Are the 3m/s² in TR1 also good for heavy vehicles?
(OICA): 3m/s² is too much for heavy vehicles. Maybe a new value is necessary, which may perhaps been specified by the vehicle manufacturer.
(Sekr): Do we assume, that at every failure a transition period plus the MRM should be performed?
(D): In reality, there may be failures, which cannot handle a MRM by the system.
(J-Chair): Are only CAT E systems considered at this time?
(D): Yes
(Chair): We should try to combine tests if possible.

Summary of the discussion of the necessity of the tests:
(green: test is necessary – red: test is not necessary)
