這兩天訂了2015年式508柴油款
想請教幾個自手排問題

爬文看到自手排需避免蠕行
自排開久了還真沒想過這問題

業務說目前的自手排有改善蠕行功能，是真的嗎？
如果要避免蠕行，是否只能等前車拉開距離後踩油門再滑行？

另一個問題是塞車走走停停怎麼開比較好
爬文結果是說避免讓離合器處在半離合狀態，會導致過熱
請問一下這要怎麼操作呢？
因為看不到離合器，如何確認"半離合"？

第一次碰自手排，還請各位指導一下

話說最近508即將改款，寶嘉好像不再進車了，折扣還滿殺的...有興趣可以去展間問問

跟手排開法一樣
入檔,前進---放空檔(鬆離合器)---滑行---踩煞車

開手排時,塞車時,腳還一直停在離合器踏板上的是錯的

自手排變速箱具備蠕行功能，好處在於塞車緩慢移動一下子時，只需放開煞車就會向前移動不用特別去補油門…
切換離合器的部分，因為改由電子系統來控制，所以不用擔心離合器過熱問題。

避免蠕行?原廠不就是為了車子好開,放開煞車,車子就會慢慢往前帶動(有像自排車的起步感覺),才將程式調成這樣.宣傳不也以為此賣點.

https://en.wikipedia.org/wiki/Multimode_manual_transmission 引述維基百科

Differences from an automatic car

A Multimode manual car has a clutch instead of a torque converter. As such, gear changes are noticeable, and the car rolls backwards when on an up-sloping incline.

1.Creeping(蠕行): A Multimode Manual Car creeps forward when the brake pedal is released and accelerator is not depressed, like an automatic car. This is achieved via partially engaging and slipping the clutch. (放煞車沒補油門時,引擎與離合器是部份滑動接合的)

2. Moving off from an incline(從斜坡移動): A MMT car rolls backwards when on an up-sloping incline, unlike an automatic car. To move off from an up-slopping incline, apply handbrake before depressing the accelerator slightly. Do not hold the car on an incline by depressing the accelerator pedal, as the slipping clutch will overheat and lead to clutch damage. (手煞車,手煞車,手煞車,因為很重要所以寫三次.大部分的人說難聽一點,開車都退化了,都不會用手煞車.只會油門,腳煞車,難怪車禍比以前多. 上坡不要硬用蠕行撐,前方有車停住就用手煞車.

3. Parking(停車): Unlike an automatic car, the P gear is absent in a MMT car. The car should be parked in the following fashion. In an up-slopping incline, put the gear to M1, or E, apply handbrake, and switch off the engine. In a down-slopping incline, put the gear to R, apply handbrake, and switch off the engine. On level ground, put the gear to R, apply handbrake, and switch off the engine. R or E/M1 substitute the P function in a full automatic. (基本上除非停陡坡,手煞車拉不住的疑慮,才會考慮用變速箱去卡,上坡用E/M1熄火,下坡用R檔熄火.個人是用過E檔熄火)

4. Moving off from Park(從停車狀態離開): The engine can only be started with the gear in N. To start, switch on the car to ON position (this releases the gear lock), depress brake pedal, put the gear to N (from either R or E/M1), and switch on the engine.(只有N檔狀態才能發動,如果停車前,不是停在N檔,請先紅火腳煞車再將檔位換至N檔再發動)

5. L/1 and 2 gears in a full automatic: The MMT does not provide L/1 and 2 gears as in a full automatic. One action of the MMT system is that it detects the gradient of the slope that the car is situated in. On a down-slopping incline and if the brake pedal is depressed, it automatically selects a lower gear to produce engine brake, which has the equivalent effect of L and 2 gears in a full automatic. L and 2 can also be substituted with E1 and E2 (not available in Aygo) or M1 and M2 gears in a MMT car. To select E1 or E2, put the gear to E, and use + and - pedal flaps on the steering wheel to override the computer selection. E will change to E1/E2/E3/E4/E5/E6, depending on the gear selected. Downshift to E1 or E2 as appropriate to simulate L and 2 gears in a full automatic. To select M1 or M2, put the gear to M, and use M- gear to downshift the gear to M1 or M2.
6. Kick-down: In E mode, the kick-down function in a full automatic can be similarly activated in an MMT car. Additionally, the kick-down function can be manually activated using the - pedal flap on the steering wheel in E mode. This overrides the computer setting and E changes to E1/E2/E3/E4/E5/E6. To stop the manual override under E mode, pull and hold the + flap on the steering wheel, until the E1/E2/E3/E4/E5/E6 changes back to E. Alternatively, wait for the next computer activated gear change.
基本上5,6是說明變速箱的降檔,昇檔,大腳油門的說明.說實在,在適當的速度自己控制檔位最快.

7. Reverse(倒車): The car reverses as in an automatic car. To reverse, depress brake pedal, and change the gear to R. Gradually lift off the brake pedal to allow the car to creep backwards. On a down-slopping incline, the creep function, simulated using the slipping clutch, is not sufficient to prevent the car from rolling forward. In this case, the car must not be held still using the accelerator pedal, as the excessive clutch slipping will lead to clutch damage. Handbrake should be instead applied, and the accelerator pedal should be depress slightly. (斜坡往上倒車,還是要配合手煞車,避免蠕行過度造成半離合的負擔)

8. Gear change(檔位變換): The gear change in MMT is noticeable, unlike in a full automatic car. Under E gear, the car will automatically change the gear depending on speed and gradient information. It is recommended that the accelerator pedal should be momentarily lifted off during gear change. A constant throttle can also be maintained on the accelerator, and gear change can still occur, although the car will feel noticeably more jerky during gear change than in a full automatic.(檔位變換的感覺還是明顯的,建議換檔時回油門一下,避免頓剉感)

看到重點了嗎?
其實蠕行的好處就是在停車,或離開停車處的微調整,一般的平面的微跟車,但是在斜坡時會造成半離合器的負擔,連續使用容易熱(開手排車反而沒這缺點,因為扭力不夠一定要補油門不然會熄火).
其實真的就是和開手排車一樣,如果和前方車距不會太遠(大概一兩公尺),我只會用半離合器.當然扭力不夠或距離拉開時是一定是補油門的. 基本上開手排車是不會跟車太近的原因也是如此.

我自己也有一台手排的,只有停車時會半離合
個人認為蠕行只是為了方便停車用
變速箱過熱會自動停止蠕行功能(遇過2次了)
其他就不多說了,請自行判斷!

比較難判斷的是在長下坡滑行，純手排車就能準確的控制離合器要不要接合，維持檔煞配合一點煞車就OK，但是自手排在退檔時的空檔或是滑行時想補點煞車的時候，有時會出現似乎電腦為了配合煞車踩下而退開離合器的感覺，導致原本的檔煞效果消失，車子在那一瞬間有一種突然變輕要滑下去的力量

看來短時間蠕行是沒問題的
再來就是等交車後多練習
希望早日習慣獅子的習性~
有心得會回來分享!!

用點踩煞車即可,其會在期間自動降檔
