If you do decide to use car filler then don't try to fill the hole all in one go. Fill the majority of the hole leaving it low to the surface by a few millimetres. When this has set then apply as little as possible to fill the remainder to the surface using the applicator/spreader that will come with the filler to get it as smooth to the rest of the top without leaving to much residue around it. The laminate has a very thin decorated surface and will not take much in the way of sanding down so try and get the best finish you can when applying the last coat of filler. Have some cellulose thinners to hand to clean away any residue of the filler around the the repair before it sets.

Experiment with the mixing ratio of the filler before you fill the hole as it will normally set with a beige to pinkish colour and you may be able to get nearish to a colour that is not to in your face.
 
Milliput putty is also excellent. very smooth finish. is available in different colours now I believe.

I had a hole in a side storage cupboard, it was underneath so I thought I would try filling it.
I used Araldite glue and put a little bit of paint in it, it would need some mix adjustments if it was on show, filled hole and covered with sellotape (because it was underneath). It didn’t come out to bad.
I would try this if I get a hole on the top surface.

Looking at your damage again, you could lift the damaged bits out and put them on the glue.
 
I had damage on my granite look work surface . I used car filler to just below the surface, Finnish with the work surface joint compound which is available from B&Q in several colours (I mixed 2 to get a good match) I added several bits of coal grit as my serface has a black fleck in it. The end result is very acceptable, plus because the filler is meant for work surfaces you do not have to do any further sealing
 
I did a similar dent in a caravan worktop, I used white Gel Coat filler and tinted it with a tiny drop of Humbrol black model paint. Could hardly see it afterwards I was very pleased with the result.
 
I used to work for a major worktop supplier, how to repair was a common question. Unika Colorfill is a specific worktop joint sealant and filler available in a huge range of colours. If you've got a local worktop supplier they will probably stock it, or you can buy it online but that makes colour matching difficult. You'll never get an exact match due to the fleck though, but you'll get a good one to the base colour.

If the result is not acceptable, then Stockmart Plastics in Portsmouth do a caravan table recovering surface - new laminate over the top - so long as you're okay to not match any other laminate the same as that elsewhere in the van. Most laminate fabricators would do this, but Stockmart are more likely than most to have a suitable size offcut, laminate usually comes in 10' x 4' sheets and can be pricey.

All depends on how fussy you are and how exactly matching and seamless a finish you require! I think personally I'd try to dig the broken pieces out and reset them in the correct colour Unika Colorfill. You don't need to buy the special solvent that they sell - pure acetone nail varnish remover will do the job just fine, I've not tried it but electrical contact cleaner will probably work as well - you'll need some to both clean everything to begin with and to wipe over your repair before it sets to blend it in.

I had a dent in a similar colour worktop in my old Swift. I used Gorilla Glue to fill it. The glue foams up a bit so I did several layers, letting each dry and foam up a bit then kept trimming it level with the surface. It leaves a porous finish, so just kept going over it with tiny bits of glue, finally cutting it level with a sharp craft blade.
The finish was almost invisible and really only I knew here it was.
 
Wicks the builders merchants sell a range of worktop repair kits called Unika Colorfill with a choice of about 8 finishes at £10.00 but never tried them.
